Short story:
My fuel pump quit working. I didn't have time to wait for a walbro 255 lph pump and the factory one is like 125 lph or something. As a Toyota tech, I've installed superchargers on Tundras that are Flex Fuel. They say the pump in the fit kit isn't required as it's the same as the one in the tank already. It's a denso pump that puts out 320 lph (from what I've read). I have one and I'm about to install it, but I just thought about if it'll be ok.
Is that too much for the stock regulator? I have 10.6:1 CR, stage 2 cams yada yada yada. No Adjustable FPR, no gauge, stock injectors, stock rail. I just don't know if the regulator can flow enough that the pressures don't climb to dangerous levels.
