OVERVIEW
Genuine VW/Audi fuel pump and fuel tank module sealing ring, part number 1J0-919-133-B. This red perimeter seal closes the joint between the matching in-tank fuel-delivery or sender flange and the fuel-tank opening. It belongs at the module mounting flange, where a properly seated seal helps keep liquid fuel and fuel vapor contained while the retaining ring secures the module.
Technical details
- Original part number: 1J0-919-133-B / 1J0919133B.
- Red formed sealing ring; exact sealing profile shown in the supplied source photos.
- Service use: fuel pump / fuel-level sender flange sealing on the confirmed applications below.
- Single-use seal: Volkswagen specifies that the removed ring must not be reused or reinstalled.
- One sealing ring supplied. Fuel pump, sender, tank, retaining ring and service tools are not included.
Common reasons to replace
Replace this ring when its module flange is removed for fuel-pump, sender or tank service. A seal that is nicked, twisted, swollen, flattened or installed unevenly may no longer close the flange joint correctly. Confirmed leakage or a damaged seal seat is also a reason to inspect and renew the seal as part of the correct repair.
Fuel odor, wetness near the access cover or an evaporative-system fault can justify inspection, but they do not prove this ring is the cause. Cracked module housings, line connections, a damaged tank opening and other evaporative-system components can produce similar symptoms. Replacing the ring will not repair an electrical pump fault or an inaccurate fuel-level sender.
Installation and service notes
Have fuel-system service performed using the factory procedure for the specific vehicle. Keep the tank opening and module clean, inspect the sealing surfaces, and install a new ring in its designated seat without pinching or rolling the profile. Align the flange correctly and use the prescribed retaining-ring tool and tightening specification.
Follow the required pressure-relief, electrical-isolation and fuel-handling precautions, then check the repaired joint for leaks. Match the VIN and installed flange before ordering; similar-looking rings can have different profiles. Some tank arrangements use more than one ring, so confirm the quantity needed for the service being performed. This listing supplies one ring.
