Fuel Problem

[Chris32]

I have a problem with the fuel tank/pump on my car

I attended a trackday/driver training day at Mallala on friday, and suffered problems where I was loosing fuel from somewhere

I took my pump out to find that the rubber seal (like a big ring) has been split and was allowing fuel to leak out.

A mate of mine was behing me and said there was fuel coming off my back right wheel too, and my fuel filler cap kept coming un-done as well, also leaking fuel

Does anyone else have these problems?

Cheers, Chris

Well,

What most people would do is replace it

I've seen on ocasions when the seal expanded and would't fit. so it was leaking out everywere. Replaced it and havnt had a problem since.

I will replace the seal, what about the fuel filler cap, I have pinched one of my R31 wagon, it seems to have much more thread on it and a much better seal, so hopefully that will work too

Dont worry the red hot exhaust is on the left rear, the fuel vapour out the right back just makes the car look tough:thumbsup:

Id be checking the fuel filler neck, a lot of imports have poorly installed necks from compliancing

very good point mate, didn't even think about that!

I will give it a look tonight

Can get replacement fuel caps from any servo..

Little surprising that that seal on the pump side of the tank causes that much difference as I though the bolts would give a pretty good seal there.. and I can't really see it splashing out unless fuel was really slapping against the top there. The tank either must be very full or its something else.

I'd just use some form of petrol tollerant sealant on the ring there..

once your pull the pump out the seal expands and it very hard to put back into its groove, so if your not very carefull it will pinch and leak

[Chris32]

Yeah, my sealing ring was split completly, so no seal at all.

I am going to try and find some rubber and make my own seal, something a bit better

Maybe put the seal in fuel while your chaning fuel pump etc?
