the problem with the regulator at the pump it doesn't circulate the fuel up near the carburetor. The magnafuel pump has a return at the pump but that didn't help with the fuel getting to hot and boiling. I put a return regulator at the fuel log and its been good ever sense
I can't imagine temp is a problem unless you're dealing with a really small tank. I never had any temp issues with my setup (I think it was 10 gallons), hot lapping, in August. Even still, how hot does the fuel need to get before it causes a timing issue?
