OK, so here's my scenario....
I've got a summit 16ga fuel cell with anti slosh foam and sump.
I've got a walbro 255lph (67gph) external inline pump
[see where the fuel pump sits?]
The walbro unit is gravity fed, so it needs to be mounted either at the source level or below for best performance. However, with this setup it hangs low and outside of the fuel cell box, and is visible to the naked eye if one bends down, or looks through the wheel gap. I would like to eliminate this and flip my fuel cell so the sump is facing forward, but there isn't a lot of room.
I was pondering last night, and thinking of surge tank setups... minus the tank. Have a low pressure flow pump feed from above the source through a couple of filters to the high pressure pump, possibly mounted in the engine bay.
Flow is flow, right? So a 70gph low pressure pump does not require to be gravity fed, and should be able to provide ample fuel straight to the walbro unit, which is 67gph. Would this setup work, or should I figure out how to replumb the system with a surge tank, costing me another 400 bucks in tank, lines, fittings, etc. Which I don't want to do.
