Drain the tank, then add clean water in measured increments and let each step settle before you read the aircraft. A sound line follows every step promptly and lands where the water says it should. A line with a restriction, a crushed section or a trapped slug of air falls behind and then catches up in a jump. If instead the number is wrong by roughly the same amount at every single step, the fault is past the hose, in the gauge or its calibration, and a new hose will not fix it.\u003c\/p\u003e\n\u003cp\u003eThen take the same water back out in steps and write the numbers down again. What you are looking for is whether the reading comes down the same way it went up. A clear line equalizes in both directions and gives you matching figures at matching levels. A partially collapsed or residue-narrowed bore resists flow, so the reading trails the true level going up and trails it again coming down, and the two sets of numbers do not agree. That disagreement is the cleanest evidence this part produces without taking anything apart.\u003c\/p\u003e\n\u003cp\u003eOnce it is off the aircraft, judge the line on the bench before you fit its replacement. Hold it up to a light and look down the bore for a haze of dried product, a scale ring near a fitting, or a section that has gone opaque. Flex it slowly along its whole length and watch the outside of each bend. A healthy hose curves. A hose that has gone hard folds flat at the bend instead of curving, and a hose that folds flat on the bench is folding flat somewhere in the routing every time the airframe moves.\u003c\/p\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cp\u003eThe liquid level gauge hose module is designed to do one job in the spray tank and its covers, sensors, and connectors and do it to specification: sealing, venting, and metering the liquid payload at the tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe module:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eServes the spray tank and its covers, sensors, and connectors of the DJI Agras T100 exactly as the factory intends\u003c\/li\u003e\n\u003cli\u003eSupports sealing, venting, and metering the liquid payload at the tank\u003c\/li\u003e\n\u003cli\u003eMaintains the tolerances and interfaces the surrounding parts depend on\u003c\/li\u003e\n\u003cli\u003eWithstands the chemical, vibration, and washdown environment of agricultural work\u003c\/li\u003e\n\u003cli\u003ePreserves the sealing and protection strategy of the platform\u003c\/li\u003e\n\u003cli\u003eKeeps failure modes visible and diagnosable instead of mysterious\u003c\/li\u003e\n\u003cli\u003eRestores factory behavior immediately upon correct installation\u003c\/li\u003e\n\u003cli\u003eProtects the more expensive components it works alongside\u003c\/li\u003e\n\u003cli\u003eCarries the exact DJI specification for its position\u003c\/li\u003e\n\u003cli\u003eSupports safe, predictable operation under full payload\u003c\/li\u003e\n\u003cli\u003eEliminates the guesswork of near-fit substitutes\u003c\/li\u003e\n\u003cli\u003eKeeps the aircraft inside its designed maintenance program\u003c\/li\u003e\n\u003cli\u003eHolds up across a full season of professional duty\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFunction on the T100 is a chain: spray system performance depends on the spray tank and its covers, sensors, and connectors, and the spray tank and its covers, sensors, and connectors depends on every part in it holding specification.

Empty the tank, run clean water through the spray system, then drain it again so you are not opening a fitting onto concentrate. Even a fully drained tank leaves liquid trapped in a low section of hose, so put a rag and a catch tray under the joint before you loosen it and keep it away from connectors and from anything painted or anodized.\u003c\/p\u003e\n\u003cp\u003ePhotograph the routing before you pull the old line out, and get the detail rather than a general view. Which side of each bracket it passes, whether it runs over or under the harness, how the fitting is clocked, and where it is retained. A gauge line reads from where it sits. Re-route it with a new high spot in the run and you have built an air trap that was not there before, and the aircraft will then read wrong in a way that looks nothing like a hose problem and will have you chasing the sensor.\u003c\/p\u003e\n\u003cp\u003eHold the fixed half still while you work the fitting. Put a wrench or a firm grip on the boss or the sensor body so the torque goes into the joint and not into the part the joint is threaded into, and never turn the fitting by twisting the hose. Small threaded plastic fittings cross-thread easily and quietly, and when one strips it usually takes the expensive half with it. Start every thread by hand, and if it does not turn freely for the first couple of turns, back it out and start again.\u003c\/p\u003e\n\u003cp\u003eVerify with clean water before any product goes near it. Fill the tank in stages and watch the reported level rise smoothly rather than in steps, which tells you the line has purged itself of air and is following the tank. Then leave it standing full for a while and come back with a dry hand and a clean rag: run them along the hose and around both fittings and check they come away dry. A joint that only weeps under a full head of liquid will not show itself in the first minute after assembly.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eError messages or warnings referencing this system in the app\u003c\/li\u003e\n\u003cli\u003eIntermittent operation that worsens with temperature or vibration\u003c\/li\u003e\n\u003cli\u003eFunction loss in the system this module serves\u003c\/li\u003e\n\u003cli\u003eVisible corrosion, moisture, or chemical residue at connectors\u003c\/li\u003e\n\u003cli\u003ePhysical damage to the housing after an impact\u003c\/li\u003e\n\u003cli\u003eErratic readings or behavior the aircraft cannot self-clear\u003c\/li\u003e\n\u003cli\u003eFailures that appear under load but pass on the bench\u003c\/li\u003e\n\u003cli\u003eBurnt smell or discoloration at the module\u003c\/li\u003e\n\u003cli\u003eRepeated faults after connector reseating\u003c\/li\u003e\n\u003cli\u003eFunction dropouts during arm fold or unfold\u003c\/li\u003e\n\u003cli\u003eBehavior that started after a hard landing or transport\u003c\/li\u003e\n\u003cli\u003eAge and hours — electronics in this environment are not lifetime parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat kills spray system modules: the compounding of ordinary duty.

Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfirm before you order:\u003c\/strong\u003e this is DJI part BC.AG.SS001121. Check the label on your old liquid level gauge hose module or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.\u003c\/p\u003e\u003cp\u003eA level that reads full and stays there while the tank visibly empties means the path to the gauge is closed rather than merely restricted. The usual causes are dried product that has built a plug at the narrowest point, a section that has been crushed under a clamp or against structure, or a fitting that was tightened until the bore pinched shut. The aircraft is not lying to you deliberately; it is faithfully reporting a level that stopped changing when the line stopped flowing.\u003c\/p\u003e\n\u003cp\u003eA reading that is close to right at the start of a load and increasingly wrong as the tank goes down is a restriction rather than a blockage. The tank level is changing faster than the line can equalize, so the error grows with the rate of change. This is the version that costs you product quality, because it is worst at the end of a load, which is exactly where the aircraft is deciding whether there is enough left for another pass.\u003c\/p\u003e\n\u003cp\u003eA reading that is sensible on the ground and jumps around in flight almost always means air in the line. Air is compressible and liquid is not, so a slug of air turns the reading into a function of how the tank is moving rather than how much is in it. It will look worst in turns, on climb-out and after a firm set-down, and it will often settle back to something believable once the aircraft is parked, which is what makes crews blame the sensor.\u003c\/p\u003e\n\u003cp\u003eA wet streak down a hose run, or a pale crusted deposit that keeps coming back at a fitting after you have cleaned it off, is a leak and it costs you twice. The reading goes wrong because the line no longer holds what it is supposed to hold, and product is being deposited on structure and connectors where it dries, concentrates and works on whatever it lands on.

The time to buy it is before the season, not during the failure.\u003c\/p\u003e\u003cp\u003eInspect the tank port and its seal while the line is off, because the hose is the cheap half of this joint. Look into the boss for thread damage, a witness mark or flat spot where an over-tightened fitting has deformed the seat, dried product packed into the threads, and any crazing or star-cracking radiating from the port in the tank wall. A port that has been chased by a cross-threaded fitting will leak with a brand new hose on it and will keep leaking until it is addressed.\u003c\/p\u003e\n\u003cp\u003eCheck the gauge or sensor end and its electrical connector at the same time. If liquid has been travelling up a weeping line it does not stop politely at the fitting. Look for residue crusted inside the connector shell, green or white corrosion on the pins, moisture sitting behind the seal, and a wire run that has been wicking. An intermittent that survives a hose replacement is very often sitting in that connector, and it is a two minute inspection while you already have access.\u003c\/p\u003e\n\u003cp\u003eWith the tank drained and the area open, go over everything else on the same sheet before you close it up. The cover seal, the waterproof permeability vent cover, the clips and the tank lanyard have all breathed the same chemistry, seen the same sunlight and taken the same vibration for the same number of hours as the hose you are replacing. Rubber and plastic age by exposure rather than by cycles, so when one of them has gone the others are not far behind.\u003c\/p\u003e\n\u003ch2\u003e💡 Why This Part Matters\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eEvery acre the T100 covers depends on the spray tank and its covers, sensors, and connectors doing its job — and the spray tank and its covers, sensors, and connectors depends on parts exactly like this one.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed liquid level gauge hose module is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.\u003c\/p\u003e\u003cp\u003eThat is the case for OEM and the case for stocking ahead. The OEM module fits the first time, behaves the way the platform expects, and carries the exact specification the spray system was engineered around — DJI material number BC.AG.SS001121.

A hose left standing full overnight, over a rained-out weekend or through a shutdown is soaking rather than merely wet, and the compound is absorbing whatever is in there the whole time. Rinsing the spray system at the end of the day and draining it so the line empties is the single cheapest thing an operator can do for this part, and it costs a few minutes at the end of a shift.\u003c\/p\u003e\n\u003cp\u003eTreat a spare the way rubber and flexible plastic want to be treated. Keep it coiled loosely in its bag, out of direct sunlight, cool and dry, not crushed under heavier parts in a bin, and away from solvent fumes and from electric motors or welding gear, because the ozone those throw off cracks flexible line that is sitting on a shelf doing nothing at all. Do not force a cold coil straight before fitting; let it come up to shop temperature and it will take its shape without stressing the wall.\u003c\/p\u003e\n\u003cp\u003eDo not cut a length of clear tubing from the shop roll and call it a repair. What this assembly supplies is a specific bore, a specific wall stiffness that resists collapse at the bend radius the routing forces on it, and a compound chosen for the chemistry it has to carry, plus fittings that seal against the parts they mate to. None of those are visible. A look-alike will fit, will look tidy, and will give you a measurement system that behaves differently under vibration and ages on a different schedule.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.

Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know my liquid level gauge hose module needs replacing?\u003c\/strong\u003e The common signs are: error messages or warnings referencing this system in the app, intermittent operation that worsens with temperature or vibration, and function loss in the system this module serves. Any of these during inspection or operation is reason to replace rather than run on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat causes this module to fail?\u003c\/strong\u003e Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I confirm the diagnosis before ordering?\u003c\/strong\u003e Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number BC.AG.SS001121 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does installation and verification look like?\u003c\/strong\u003e Replacement is a standard shop task on the T100: open access to the spray tank and its covers, sensors, and connectors, document connections and hardware positions, swap the liquid level gauge hose module for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this the same part across the listed models?\u003c\/strong\u003e Yes — the supplier lists this exact component for DJI Agras T100 \/ T70P, so one part covers those platforms. Select your model when ordering; the material number is the same.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy tank level reads full even when the tank is nearly empty. Is that the hose or the gauge?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNearly always the hose, and you can separate them without ordering anything. Drain the tank and add clean water in measured steps, letting each one settle. A gauge that has failed usually reads wrong by a consistent amount at every step or reads nothing at all. A line that is plugged stops responding entirely, so the number freezes and stays frozen while the water level obviously changes. A frozen reading with a live gauge points at a blocked or crushed line.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe reading is steady on the ground but jumps around once we are flying. What causes that?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAir trapped in the line. Liquid does not compress and air does, so a slug of air turns the reading into a report on how the tank is sloshing rather than how much is in it. It shows up worst in turns, on climb-out and after a firm landing, and it usually settles to something believable once the aircraft is parked, which is why it gets blamed on the sensor. Look for a high spot in the routing or a joint drawing air.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I have to bleed or prime the new line after fitting it?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFill with clean water rather than product and watch the reported level come up as the tank fills. If the number rises smoothly the line has purged itself and is following the tank. If it comes up in steps or hangs and then jumps, there is still air in there, and the cause is usually a high spot in the routing rather than the hose itself. Re-check the run against the photographs you took before removal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat length is the hose and what size are the fittings?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDJI does not publish a length, bore or thread size for this module in the parts documentation, so do not order by measurement and do not try to match it from a catalogue of generic tubing. Order by the material number, BC.AG.SS001121, and lay the old assembly next to the new one on the bench before it goes on the aircraft. If the removed part is missing or destroyed, confirm the position on your parts diagram instead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the DJI Agras T100 OEM Liquid Level Gauge Hose Module (BC.AG.SS001121) also available in Canada?\u003c\/strong\u003e Yes.
