    pro max is a submersible type pump.. probably won't run long "exposed" .. unless its tha early efi stuff which is probably wore out already.

    I'm running out of fuel in the rail on a good long run with my Promax. It's still stock Vst but the high pressure pump is NOT in the vst tank. It sits in front of it. I'm thinking of getting rid of the tank and diagram pump and mounting a small lift pump in the boat to feed the high pump.
