The High-Pressure Oil Pump (HPOP) is the heart of the HEUI (Hydraulically Actuated, Electronically Controlled Unit Injector) fuel injection system used on both the 7.3L and 6.0L Powerstroke. When the

The 6.0L Powerstroke can tow extremely well, when it’s healthy. The problem is that towing exposes every weak link. Heat climbs, boost demand increases, fuel demand goes up, and the high-pressure oil
