Dual Fuel Pump Theory
What is the main reason for someone to want to use a dual fuel pump setup? Why would someone choose this option instead of running a high flowing single pump? Seems like it's far and away overkill... Say for a car even chasing 600whp. Please enlighten me.

Redundancy, the ability to stage pumps on demand, and opening up the world of surge tanks etc. Also last I actually looked dual 044s were still the best bang for the buck with a real OEM backing it with regards to flow at higher pressures. This is not to knock any of the other well known pumps by any stretch.

E85 requires about 30% more fuel, so more pumpage is needed. I know I went a little over kill though. I'm running a Radium Surge tank with 1 lift pump and 2 pumps sending the fuel forward. All 3 pumps are Walbro 450. The second pump that sends the fuel forward doesn't kick on till 4000 RPM.
