Sealing a fuel tank
Noticed a strong smell of fuel when i was in the garage earlier and upon inspection i found a fuel leak from the in tank fuel pump on my BEC MK
Indy.
Upon removing the pump i found that it does not run an o ring to seal it but had a very small amount of rubber type sealant.
What is the best thing to use to make a good seal between my pump and tank ??

I used an ali \ metal \ chemical weld for a crack in my tank which has worked a treat.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Make a cork gasket, the chemicals in the fuel will perish rubber.

Viton is the stuff these days. Nitrile does not cope long term with the ethanol in petrol. Even the cork gaskets use a nitrile based rubber to make
them, I checked all sorts of places (on the net, in shops you just get told "that is what we have always sold" for the specs. Saying
that, there was a viton based cork gasket material, but not easy to buy...
Viton O rings easy to get, try "simply bearings"

Hylomar blue if you want silicone sealant style stuff that is fuel safe.
