Perhaps Seal-All? I have used it to fix fuel leaks before. Works great with fuel.

A cake of hand soap will work wonders for sealing gas leaks.

A little bit of water and make a thick paste - then mold it around the leak area or seal and let it set.

There are bulkhead connectors made for this purpose. Google "fuel pump wire bulkhead" and pick a style that you're comfortable with...

Aircraft Spruce carries a fuel tank sealant called Pro Seal. Sealed my aluminum tanks in my airplane with it. It's a 2 part mix. You would have to buy a qt.
