Gas leak after new o ring replacement - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Recently bought a new o ring from Nissan for my s13 coupe. When I turn on the car and check the fuel pump you could see the outer rim of the fuel pump fill up with gas quickly and the right side of the gas tank just leaks so much. I even just primed the fuel pump and see it barely fill on the rim the fuel pump but no gas leak.

I’ve been stuck on this for a while, if anyone can help I’d greatly appreciate it

ok, so did you seat the o ring correctly and tighten all those small bolts back down? are there any leaks from the fuel lines? does anything look bent? try also pressurizing tank with compressed air and see if there are any other leaking areas eg: crack in tank...

:

your fuel tank leaks??? i'd start by replacing that first!

what o-ring were you replacing? the one that goes on top of the tank where the fuel pump hanger bolts on?
