Thread: Does a blower motor w/ carbs need a return fuel line???

Tweet

When you get a fuel system big enough to run a blown '92 you'll need at lest a 1/2 or possibly 3/4 fuel line and a big bypassing regulator ( possibly hooked up after your float bowls)to return excess fuel at lower throttle settings.
The holley pumps probably won't be big enough

Of course if you use a mech engine driven pump this all changes

Thank You Blowby & Jerry....

Jerry, what kind of electric fuel pump & fuel filter would you recommend? And I will run 3/4" line if you think it's necessary {is that what they refer to as a
-10 line?}. I'd rather be safe than sorry. What size return fuel line would you use?... You mentioned a mechanical engine pump? Would this feed this size engine? If so, what make/model would you use? THANKS Bill
