Fuel Pump Upgrade

[Alpha D]

Thats a good way to look at it as well. I brought that point across and he said a stock oem pump still could keep up with the demand. Which makes me wonder well if your FPR is set to maintain a certain pressure, is he positive the stock pump can adapt its speed to maintain that pressure (In a none variable speed pump)?

Since you can only provide a max amount of maybe 14. something volts to the pump by rewiring, and the motor will only be able to go so fast. Then how is it possible for the pump to pump the needed amount of fuel to maintain that pressure given that certain amount of voltage?

I guess maybe looking at the internal make up might make a difference? Time to look at the guts of a fuel pump? Show the difference in mechanical make up.
