Re: Bad fuel pump or regulator
67 econobox, I have heard what sounds like fuel boiling in my tank also. The fuel that is returned to the tank is very hot. In addition I have my exhaust pipes turned down before the axle. It definitely can add some hot temps to the tank area. I may point them outward a little more, but don't like them pointed at the rear tires. Ugly things can happen. I ordered a barry grant fuel line cooler. I was planning on installing it on the return line to the tank. I think the fuel is so hot it is cavitating in the pump in the tank. Hopefully these two things will suffice.
