Fuel resistant glue for bonding rubber to metal?

[jimson]

From memory I bought the alloy pipe pretty much the right size, cut it to length  and put it in the lathe to make a channel so a O ring could fit, but it was to tight. If you look at one of the pics theres an O ring at the top of the pipe it seats really well in when the cap is pushed on & turned. jimson

So the alloy tube is an interference fit, or soldered into the tank? and the cap locates onto the alloy tube?

I've only used the alloy pipe on the lid. The opening on the fuel tank, is just from carefully removing the old locking cap. jimson
