Clair,
    In adding any fittings to the fuel tank the most important thing is 
ya just gotta have a perfect seal!
... Obvious I know, but fuel tanks, lines and couplings I am very wary 
of and careful with! ... fuel leaks are no laughing matter, be careful!
I would tend as far as possible to use a "belt and braces" approach to 
any such mods, and not rely on a single sealing method .....

Regards
Bill
