hey guys wondering what the suppply is needed ot feed the VE pump i have a holley black pump we put on my dads 1st gen but he says its only running at 9psi running but can be up to 14 so would bumping it up to 14psi make a difference or can he put a eletric pump that puts out almost 40psi and not hurt the pump? what should fuel pressure be whil;e driving the truck. is afc mod keep the truck drivable or big losses in mileage? pros and cons of this mod
