OVERVIEW
Seal the fuel tank service flange
Genuine VW/Audi 1J0-919-133 seals the designated fuel pump or sender flange to the tank opening. A correctly seated seal helps contain fuel and vapor at this service connection.
The molded sealing profile must match the tank neck and flange it supports. This listing supplies the dry seal individually; the fuel pump, sender assembly, retaining ring and fuel are separate.
Technical details
- Complete factory number: 1J0-919-133.
- Factory specification: factory molded fuel tank flange seal, number 1J0-919-133.
- Design: shaped sealing ring for the assigned pump/sender service opening.
- Quantity supplied: one individual fuel flange seal.
Some tanks have more than one service flange and may use different seals at different positions. Identify the assigned opening and original seal number rather than selecting by vehicle model alone. The retaining ring supplies clamping force while the gasket provides the sealing interface.
Common reasons to replace
- The original gasket is disturbed during pump or sender replacement.
- The seal is torn, pinched, hardened or permanently flattened.
- Inspection traces fuel odor or seepage specifically to the flange sealing joint.
Check the flange, tank neck and retaining hardware for cracks or distortion. An evaporative-system fault or fuel odor can have other causes, including a loose connection or damaged pipe, so confirm the source before replacing parts.

Installation guidance
Follow the factory fuel-system pressure relief and electrical isolation procedure. Work with appropriate ventilation and ignition-source controls. Clean the joint, seat the seal without twisting or pinching it, and secure the flange using the specified installation method and tool.
Check the completed connection for leakage using the prescribed service procedure. Reconnect any lines and wiring correctly and complete the required system checks before operation.
Ordering information
One individual Genuine VW/Audi 1J0-919-133 seal is supplied. Compare the original molded profile and flange assignment; order a separate retaining ring or flange assembly when those parts are damaged.
