[RICK LAKE]

Pman1961 I race 98% track and run 2 systems of pumps, filters and check valves. I only run 1 pump at a time unless needed. Backup plan.
#8 or #10 line is the best way to go. better to have too much supply than running lean on long runs. Wrapping and or shielding the lines from tank to the motor is also needed. Clamp the lines to the frame every 12" to stop vibrations.
Rubber hose keep to minium because of the ethohol in the gas eats rubber over time from the inside out. Takes about 8-10 years for failure, repaired twice between fuel outlets and fuel pumps.
I would recommend a pressure regulator of 6 psi with a #6 return line to the tank. This will pervent vapor lock when racing.
Put an electric fuel pump as close to the fuel cell or tank as possible. Some of these pumps don't have good vacuum. If you are going to race, get a fuel cell that is SEFI aproved.
Better to have more than is needed, then not enought when running.
Also look into running marine 4" fans under the hood to help remove hot air in the motor bay. Simple hookup with 2 plates to locate fans and blow air out louvers on front fenders. It helps alot and knocks down the temp about 20-30 degrees. Good luck. Rick L.
