Hey guys, I need a chunck of info from y'all...I am working on plumbing my fuel delivery system (back to front) and lo and behold once I got to the mechanical fuel pump on my '82 2.8L Chevy motor I found that there is a fuel return line...Larger 3/8" line into pump from tank, steel formed line out to carb.(never disconnected this one), and then a smaller 5/16" line that I assumed was the return to the tank...BIG QUESTION IS...does that return line need to get back to the tank...or is more like a vent for the pump and there will be NO fuel traveling thru it??? Thanks guys!!!
