Message: [QUOTE="Dieselfever, post: 611695, member: 171"] I've had 200/30's in my '97 for over 5 years now, My fuel system is a stock SD pump that feeds the back of the heads with the DI fittings and returns from the front of the engine to an Aeromotive regulator. My pressure is set at 65-67 psi and will drop to 62-63 psi at WOT in my hottest programs (Dyno'd 401/807 in '09). That was with a factory 15 degree HPOP When in good working order the factory SD pumps have enough volume to supply those injectors IMO, its just how you get it from the tank to the engine. Your probably reading pressure at the factory fuel filter housing and I know the factory fittings where the lines from the bowl connect to the head are very restricted, so you can figure that if pressure before the heads is dropping then the actual pressure in the head is less. Swamps recommends no less than 40 psi to the injectors(no matter what size). I would find a way to hook your fuel pressure gauge to the plugged 1/8" passage on the front of the passenger side head and check pressure again, then see how much pressure is actually at the injectors. Best case scenario you may have a weak factory fuel pump. [/QUOTE]
