If you own a 1994–2000 7.3L Powerstroke, you’re likely missing the benefit of the low-pressure oil mesh screen found on later 2001–2003 models. Most don't understand that the HPOP takes it's supply di

The 7.3 Powerstroke HPOP reservoir cover is one of those small parts that gets annoying fast when the fill plug is stripped, the cover is tired, or the reservoir needs to be topped off without making

The 7.3 Powerstroke HPOP reservoir feeds oil to the high-pressure oil system. When the factory cast reservoir cracks, leaks, or has damaged threads, it can create oil leaks in the valley and make diag

The 7.3L Powerstroke (1994–2003) earned its reputation the old-school way: simple, durable, and willing to work for a living. But even the legendary 7.3 has predictable wear points—especially now that

Good clean oil is extremely important to a 7.3L. Moreso than for most other engines. That's because the oil is used differently than with most other engines. The 7.3L injection system is more like a h

The 7.3L Power Stroke’s HEUI system runs on high-pressure oil, and the Injection Pressure Regulator (IPR) controlls how much oil the HPOP actually sends to the injectors. When the IPR is happy, the tr

The 6.0L Powerstroke platform is known for its performance potential, but also for a set of well-documented reliability concerns that the aftermarket has worked hard to solve. Across thousands of cust

The stock 7.3 fuel bowl FPR housing works… until it doesn’t. The cast threads can bind, strip, or flat-out snap if there’s contamination in the threads or the compression fitting gets over-tightened.

If you are replacing the HPOP on a 7.3L Powerstroke, having a step-by-step guide matters. These instructions cover the required parts, recommended tools, pump installation, IPR reassembly, oil refill,

If the non-serviceable plug at the bottom of your HPOP is leaking, the factory short-thread plug has likely stripped the threads in the aluminum housing. This long-thread replacement plug is made from

The 7.3 Powerstroke’s HEUI injection system relies on oil pressure to fire the injectors. Unlike most light duty diesel injection systems on the road today, where the pump (CP3, CP4, VE, VP, etc) crea

The 7.3L Powerstroke has a gift for making one leak look like another. Oil starts high, runs down the valley, follows the back of the block, coats the bellhousing, and suddenly everyone is yelling “re

The 6.0L Powerstroke gets blamed for a lot of things, but vacuum issues are usually not engine-performance problems. They’re usually 4x4 hub problems, HVAC mode problems, or electrical/vacuum control
