2007-2018 Cummins 6.7L 68RFE RevMax Billet Modified High Pressure Pump (68RFE-615BB)

The RevMax 68rfe High Performance Pump has been upgraded and modified to be able to produce over 325 PSI with proper tuning. However, you would need our RevMax 68rfe valve body to be able to achieve more than 175 PSI because of factory restrictions. Also, just because our pump can achieve extremely high pressure, does not mean that recommend more than 225 PSI in the 68rfe transmissions. All 68rfe pumps have been reworked with new valving, springs and have passed multiple vacuum and pressure tests to ensure proper operation and reliability for many years!

68RFE Billet Pump Body

We have always wondered why so much attention has been paid to the warpage of the valve body on the 68RFE and none to the pump! Transmission builders across the country (those that have access to surface plates) have known for years that the 68RFE pump is prone to warpage. Just like the valve body, the pump too doesn’t have a gasket and relies on perfectly flat mating surfaces to seal properly. When the pump is new these surfaces seal pretty good but after hundreds or thousands of heat cycles warpage becomes a huge issue. We have seen used pump bodies with up to .020” warpage and nearly every pump we inspect has a moderate amount.
