STAGE 1

EXCEEDS OEM VOLUME AND PRESSURE. THESE PUMPS GO THROUGH RIGOROUS BENCH TESTING AND IF THEY DO NOT MEET MIMINUM 5GPM + THEY ARE TORN BACK DOWN AND GONE THROUGH AGAIN. TYPICALLY THESE PUMP WILL PRODUCE 5.1-5.6GPM WHICH USUALLY PLENTY ENOUGH VOLUME TO SUSTAIN 230/100 HYBRID INJECTORS. WE DO NOT LIST THIS PUMP AS AN AFTERMARKET HIGH PERFORMANCE PUMP, BUT IT WILL INDEED SUPPORT CERTAIN PERFORMANCE INJECTORS.  IT WILL NOT SUPPORT LARGER A OR B CODE INJECTORS THOUGH.  ALSO COMES WITH A NEW ALLIANT POWER GASKET

PLEASE SELECT THE YEAR OF TRUCK IN THE DROP-DOWN MENU TO BE SURE YOU GET THE CORRECT PUMP, AS THE 94.5-95 TRUCKS HAVE A DIFFERENT FRONT ENGINE COVER, AND ALSO HAVE THE ANTI-DRAIN BACK IN THE PUMP, UNLIKE THE ANTI-DRAIN BACK FOR THE 96-03 IS IN THE ENGINE BLOCK, THE 94.5-97 PUMPS UTILIZE JIC FITTINGS, AND THE E99-03 PUMPS USE THE STC STYLE FITTINGS.

 

NOTE:

WE HAVE THE OBS AND E99 HPOP FITTED WITH A 17* SWASH PLATE TOO FOR SLIGHTLY MORE VOLUME LIKE THE L99-03 SUPERDUTY TRUCKS.

ALL OF OUR 7.3L HPOP'S NOW COME WITH STEEL THREADED INSERTS IN THE OUTLET PORTS.  THE ORIGINGAL THREADS CAN BE FATIGUED AND THE POTENTIAL TO RIP THEM OUT FROM OVER TIGHTENING THE FITTINGS IS COMMON OR GETTING BLOWN OUT DURING ELEVATED PRESSURE.
