Difficulty Refilling The Fuel Tank (SI B16 01 20)

DIFFICULTY REFILLING THE FUEL TANK

TECHNICAL SERVICE BULLETIN

SITUATION

The vehicle is difficult to refill with fuel. A blockage in the rubber hose portion of the filler pipe assembly may be the root cause.

PROCEDURE

1. Use special tool 0 495 588 (16 1 080) to hold open the flap at the top of the filler neck.

   This will avoid getting the borescope (1) stuck in the filler neck upon removal. 

2. Insert the borescope flexible camera head down into the filler neck.

   If you can see the internal check valve (ICV; item 1) at the bottom of the filler neck, the rubber hose is not collapsed and your restriction resides somewhere else in the system.

3. If you cannot see the ICV at the bottom of the filler neck, the rubber hose is collapsed and needs to be replaced.

   Replace only the rubber section of the filler neck. Do not replace the entire fuel filler neck.

   Refer the applicable repair instructions for the specific vehicle by entering the VIN into AIR or ISTA.

A new hose material started production as of August 2018. If cases are seen after this production date, please create an Info Only TSARA case with pictures.

IMPORTANT INFORMATION ABOUT THE CHARCOAL CANISTER

Removing the charcoal canister (Carbon Canister - AKF) from the vehicle to weigh it on a scale is not a viable diagnosis step.

All charcoal canisters will appear to feel heavy or weigh heavier than a new unused replacement unit because the carbon content has absorbed the fuel vapor. The increased weight is normal and is not a defect, the canister should not be replaced.

If an excessive amount of raw fuel is found in the canister and/or the charcoal contents appear to be falling out of the canister, then there may be an issue present that requires the canister to be replaced.

If additional diagnosis assistance is required, create a TSARA hotline case with a clear description with pictures of what is found and wait for their response.
