Default Fuel pressure
I'm going 140hp injectors and twins. Now I was wandering what fuel pressure do I need to keep to not starve my injection pump

AirDog with a 40psi spring would cover that... i happen to have mine for sale right now at 350 with the lines and such....

then you can do a return fitting and push it up farther than that if you have the desire...
