Re: Fuel pressure with 2 superduty pumps
Ok, my pumps are in series.
You're pumps are plumbed wrong...
You want them in PARALLEL, i.e. both suction sides hooked together (sucking from tank); both discharge sides hooked together, pushing to the heads. The idea is to increase the VOLUME of fuel available (each pump moves "X" gallons per minute). The pressure regulator will limit the pressure to your set-point.
In series, you're not getting any GPM increase... maybe just the potential for pressure increase, but NO increase in volume.
Think of it like two D-cell batteries in a flashlight: Each one is 1.5 volts, and say, 2 amps capacity. When in series (end-to-end) you get 3 volts, but still only 2 amps. When in parallel (side-by-side), you only get the 1.5 volts, but now have 4 amps capacity.
