Fuel Supply Pump

[Smoking S]

What kind of volume and pressure is needed to fully supply a 13 mm quick delivery p pump? I've got a raptor fuel pump that puts out 150 gph up to 70 psi or i have a barry grant pump that puts out 400 gph and i'm not forsure on the pressure. I'd rather use the raptor pump, but if it won't supply my p-pump fully i will use the barry grant pump.

The 150gph pump will have trouble keeping up. Make sure you use an adjustable return and not the factory one. I have used a 375gph pump and at idle I set the return for 50 psi. At 4500rpm, it would run about 40psi. As long as you are 35-45 psi under full throttle and full rpm, you will be just fine.
