Fuel System Questions
Hi All,
I'm getting my fuel system together at the moment and have been thinking of a few different ways to get things going.
I've got a VN Commodore tank with in tank pump but I'm doubtful as to whether the VN pump will keep up with the LS1's requirements.
lately I've been thinking about removing the in tank pump and having a straight pickup and using an external low pressure pump like a Holley red or Carter gold. This would then feed a 1 or 2 litre swirl pot up in the engine bay. From the Swirl pot I'd use a Bosch motorsport pump and regulator to feed from the swirl pot to the motor.
I was thinking of using an external low pressure pump as I've heard that high pressure pumps can fail when running under a light load just feeding a swirl pot.
I also thought that putting the swirl pot up in the engine bay keeps my high pressure fuel lines to a minimum and I've got plenty of room on the firewall for the swirl pot, pump and regulator.
What do you think? A silly idea? Any sugestions?
