I know he needs a whole new fuel system. I also told him the 5/16 fuel line (from the gas tank & fwd) is too small.
I am saying for now at least hook up a boost reference line so it does not run out of fuel as soon.
By the time he puts up a whole new fuel system it will probably be too late KABOOM!, just saying for now to do something in the meantime to get by, it will work better than no boost ref line, which is the way it's been & he thinks it does not do anything. http://vs57.y-block.info/fuelpump.htm
