Fuel connector leak

**knuts2au** · 2nd June 2025, 12:19 PM

TD5. I have a small leak from a push on connector going onto the FPR. Is there an O ring inside I can replace?
The line looks like it is continuous to the back of the car.

The ports which are screwed into the FPR have o-rings, google out STC4509

I would say no.
This is not a 100% certain no, tho.

There is a very thin o-ring in these quick connects, but they are so far and deep into the connector it's very hard, if not impossible to change.

You can get quick connect fittings to replace yours.

Do a search for "7.89mm fuel connector" on ebay or your preferred webstore so you can see whats available.

Because of the hard nylon line, I'd recommend that you also search for the types that have the o-ring on the fuel hose side too.

I've replaced them using a heat gun, worked fine. johnp38 alerted me(us) to a tool that helps to do this too.

It may not be the connector. The line is nylon, sheathed in rubber. If the line is leaking under the rubber, it can appear to be the connection.

Thanks for the replies, i assumed it was a strange rubber line but now i know it's a sheath i'll cut it back and have another look in case it is a split/cracked pipe.
It's right above the starter so sooner fixed the better.
