RebekahsZ Posted February 23, 2012 Share Posted February 23, 2012 I thought I had a smart idea by using a Z31 fuel pump top as an access door into my 240z fuel tank. I cleaned and sandblasted the tank, painted the top of the fuel pump and used a new o-ring. Cut a sction of the Z31 tank and had it welded into my 240z. Put it together, filled the fuel tanks, and fuel leaked all over the place when I filled the tank! Any ideas why my fuel pump lid won't seal? I don't feel a lot of resistance when tightening the top of the lid. Maybe I need to remove the paint from the lid? Maybe I need to use gasket sealer? Any sugestions appreciated.

Canadianz Posted February 23, 2012 Share Posted February 23, 2012 Not sure why its leaking, but DO NOT use form a gasket or RTV on it. Contact with fuel will swell it and turn it into jelly over time and is great at plugging fuel pumps, filters etc. Generally, causing no end of trouble for you. I don't know of any RTVs that are compatible with fuel, but I would be wary. Rob Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted February 23, 2012 Author Share Posted February 23, 2012 Thanks. I was just thinking of using RTV.... It is a new o-ring from the dealer (looks just like the old one), I wonder if the paint is a problem, or if the o-ring could be the wrong size-it takes no torque on the bolts to tighten it down flush...
