I will try metal lines since it runs the same whether I go from a gas can to the pump or the car's gas tank to the pump. I have a couple other questions. Can anyone e-mail me pictures of there lines from pump to carb. to see how it's routed. What temp. do you think is "normal" or "safe" to run at? I've seen these switches or units if I go electric pump that shuts off pump if oil pressure stops, has anyone installed one and know where they go or how they wire? I already have a battery disconnect/shut-off wired in to the console, should I have a separate one for the pump if I go electric? I know I'm full of questions, but I'm frustrated and stumped....
