Fuel pump leak - searched

[saechao04]

So I installed my walbro 255 today and now I have a fuel leak, well multiple leaks actually. So My question is why is it leaking? It didn't leak before I installed the walbro. Thanks in advance.

Did you get a new gasket and use teflon tape on the fittings? and it looks to leak alot around that broke stud so i would fix that also.

I did not use a new gasket, the rubber looked and felt fine. Teflon tape isn't suppose to be used on fuel fittings. As for the broken stud, it's been broken for 2 years and never gave me a problem.

well everyone uses teflon tape to ensure a good seal with AFPR's etc, just take into consideration you have a high pressure fuel pump now so of course the line will leak now so teflon tape will help seal the threads so no fuel passes them from a bigger fuel pump.

as for the fuel on the top of the tank the gasket may feel fine but from fuel sloshing around it will find its way out passed the gasket.

Changing pumps should not cause a leak to just appear out of nowhere, especially if that AN line was being used with the other pump.

Teflon tape should not be used. With AN and other flared fittings, the seal is made at the flare, not on the threads. Even on pipe (NPT) and other tapered threads where a sealer is needed, anaerobic sealing paste is better than teflon tape.

I would say the AN line may not be put together correctly if it is leaking there, or it may be damaged.

On the gasket, make sure the locator pegs on the gasket are fully seated in the hanger. You may have to grab them with pliers on the top side and work them into the hanger plate until the gasket is fully seated.

EDIT:

You may not have the same style gasket with the PITA locating pegs as a 1G. (can't quite tell if those holes are for them or not). Regardless, make sure nothing is up under the gasket and preventing the hanger from sealing against the gasket and tank.

Haha, it's alright, my gasket wasn't in place right actually, so I adjusted and I will try again tomorrow.
