Pete Posted August 7, 2018 Report Share Posted August 7, 2018 Hi all, Had my '39 Plymouth up on the lift yesterday and noticed that there is fuel leaking from the area of the fuel gauge sender unit. I had just filled it up and noticed the gas smell. I'll order a new gasket as I made the last one which obviously did not work out too well. I guess the new gasket will be cork or cork/rubber composite. Question: What gasket cement or sealer (if any) should I use on this gasket? Thanks, Pete Quote Link to comment Share on other sites More sharing options...
dpollo Posted August 8, 2018 Report Share Posted August 8, 2018 it should not need any sealer but if you want to be certain , a little permatex "form a gasket" will do the job. avoid silicones as bits of it may get into the tank and cause other problems.

Pete Posted August 8, 2018 Author Report Share Posted August 8, 2018 dpollo, I appreciate the reply. I ordered a new gasket and it appears to be rubber. I'll install it without the Permatex so it will be easier to remove in the future. If it still leaks I'll go with plan B.

soth122003 Posted August 8, 2018 Report Share Posted August 8, 2018 Hey Pete, Also watch the torque on the screws. To much and you can create a small gap in the area between the screws that will leak or weep on fill-up. Joe Quote Link to comment Share on other sites More sharing options...
greg g Posted August 8, 2018 Report Share Posted August 8, 2018 As stated don't over tighten,use a star pattern on the screws when you tighten, and go for two or three times around till snug, then do another quarter turn. Quote Link to comment Share on other sites More sharing options...
