quick help with fuel system direction
Hey guys. Running a 370 with a D-1SC procharger. Deka 60s (~73lb/hr @ 4 bar).
I'm converting to a return system, currently returnless
My GSS341 HP can't keep up, on my returnless setup pressure drops enough to make me not floor the truck in like 3 months.
My choices are DIY dual walbro's. I have the pumps, I have the harnesses. I was even going to have a THIRD walbro to just pour fuel on the bucket when in boost. (2nd in-tank/bucket turns on in boost as well).
Seems complicated, but offers the most 'stock' sound and performance/reliability..although with 3 pumps there is a large margin for error.
Next choice:
Stock pump Y'd into a magnafuel 4301 (will turn on at 2-4psi) that is sumped from rear side of tank (not bottom--I drive in the snow and don't want anything dragging underneath).
-8 or -10 feed goes into a Y with dual checkvalves (one side is coming from stock walbro, other side is incoming from magnafuel), and feeds the rails.
I am using an aeromotive 13109 rising rate FPR as well. -6/stock feed as return to bucket.
-----
The 3 walbro's are cheaper than the 1 magnafuel. I guess I just don't know which direction to go in. The Magnafuel seems a LOT less complicated at this point.
Any insight or push toward a selection appreciated.

And that is really enough? I've considered it. A friend of mine ran a 044 and 255 walbro and couldn't keep up the pressure. The 044 was mounted exterior. With his Magnafuel setup now he has no issues making fuel pressure.
