'77 fuel pressure issue

[siteunseen]

Question for FastWoman. Do you think if I put the biggest "T" I could find with the gauge on it in the fuel return line beside the fuel filter it would be ok? Or still restrict gas flow and decrease pressure? I'm a gauge freak. The more the better.

Can't have too many gauges!

Your fuel pressure on your return line should be nearly zero. If you do have pressure there (especially after you relieve any air pressure in your gas tank), then you have a blockage somewhere in the return line. The best place for a gauge, IMO, is inbetween the fuel filter and the supply tube to the fuel rail.

You should use 5/16" barbs -- no smaller and no larger -- for your fuel lines. Too large a barb will eventually split your fuel line, and too small a barb just won't hold the hose. I wouldn't worry about flow restriction. I know people get all freaky about flow restriction, but the fuel doesn't really flow all that fast. 5/16" is plenty adequate.
