Title: Mk5 gti where do these fuel lines go to.
Post by: T4yy18 on June 02, 2023, 08:24:31 pm

Hi
Had a problem with my mk5 gti where the fuel line to the fuel filter had popped off and has been leaking fuel while driving. Suspect the clip has broken off. The part of the filter, where ther are two fuel lines coneccted to it, do they go to the lpfp or do they go under the car towards the engine. Please let me could you also let me know about part numbers as well please?

Black line from LPFP, blue line goes back to the tank.  Other end of the filter and the tank vent line go to the engine bay.

The clip might just be gritted up and not clipped on fully. Pop it off and lube it up with WD40 or something.  The fittings are part of the entire fuel line, you can't get them separately from VW.  You would have to do a repair with fittings like these - https://www.ebay.co.uk/itm/164573802631?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338723872&toolid=20006&customid=cnlAm00XAAAAbqelRz6COUxp0MYGAAAAAA
