fuel tank selector valve

[slug]

ok guys, i have a 83 chevy with dual tanks. i just installed a electric fuel pump and regulator and im haveing a problem with the fuel pump building to much presure and flooding out the carb, even with the regulator at its lowest setting. so, i ordered a new regulator with a by-pass that will bleed off excess pressure and send the excess fuel back to the tanks. my question is, on the fuel tank selector valve there are 6 ports on it. 3ea. 3/8" fuel line ports (2 into the valve and one out) and 3 smaller 5/16"(im guessing vaper return lines). im wondering if it would be ok to use the vapor return lines (5/16") as fuel return lines.

Actually, slug, I think the smaller 3 ports on the valve is for the return line. One port feeds the selector valve from the fuel pump (or, in your case, the regulator bypass) and the other two ports redirects the feed into the dual tanks.

BTW,
there is nothing better than cutting metal with fire.......except cutting metal with electricity!!!

..... how 'bout with light!

cool, i wasn't sure if they were for vapor return or not. i ddnt know if the smaller ports wwere designed to handle liquid fuel or not.
