I am in the processing of dropping a 76 2F in my 70 FJ40 to replace my original F145. When taking the F motor out, I unhooked the fuel feed line and didn't think twice about the fact that no fuel return line existed. Now that I am hooking up the 2F, the fuel return line off the carb is lonely. Any experience on this? ideas? I suppose I can hook up a Y connector before the fuel filter and let it just feed back into the hose, but will this screw up my fuel pressure? Should I run a line back to my tank?
