CNC Fabrication Stage 1 High Pressure Oil Pump (HPOP) 94-03 Ford 7.3L Powerstroke
Description
The HPOP, or High Pressure Oil Pump, on your 7.3L is the heart of your engine, ensuring that not only are you able to build oil pressure, but to build oil pressure that drives your HEUI injectors. Without adequate volume and pressure, your truck simply won't run as it could.
Whether you've installed larger injectors, tuning, or you merely have a bone stock engine and the factory HPOP is on its way out, this Stage 1 HPOP from CNC Fab is an excellent choice. This pump exceed OEM volume and are rigorously tested, typically producing 5.1-5.6 gallons per minute.
This volume is usually enough to sustain up to 230/100 Hybrid injectors for those looking for a little performance. It will not support larger A or B code injectors. A core return shipping label is provided free of charge with each pump purchase within the lower 48 United States.

Very happy
"Very happy with the quality of part, and the quality of service. I had previously purchased a HPOP from another un named vendor. Had problems with it immediately. Then they wouldn't warranty it or even help me with it. It also didn't come with any documentation. This CNC Fab HPOP came with documentation, wonderful service so far. As well as it has made a tremendous improvement on my truck. All around very pleased so far."
