Fuel Return Line - Do I Need One?

Nope, no return... get a good out the back 15psi gague NON liquid filled, set to 6psi. I put a filter before the pump and a small inline filter before the regulator. Make sure when doing new fuel lines you blow them out good with compressed air to get any debris out of it. I had fits because I didn't blow mine out good enough and kept plugging up my regulator and my needle valve in my carb :sign6:
