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

If you’re done trusting (and fighting) the aging factory 4x4 hubs (or anything with plastic where it shouldn’t be), the WARN Premium Hub Set (38826) is the industry-standard fix: all-metal constructio

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’ve got oil pooling in the 7.3 engine valley (under the fuel bowl/HPOP area), the HPOP is always on the suspect list—especially the rear/end plug and the high-pressure discharge fittings. You ca

The blue spring upgrade exists because the 6.0L Powerstroke has a fuel pressure problem that usually starts small, stays hidden, and eventually gets expensive. From the factory, the regulator in the f

The 6.0L Powerstroke gets blamed for everything. Some of it is fair. Some of it is just people ignoring $40 problems until they turn into $4,000 problems. Not every fix needs head studs, an EGR cooler

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,

The 7.3L Powerstroke ran long enough that people started treating all of them the same. That is how wrong parts get ordered. A 1996 OBS 7.3 and a 2002 Super Duty 7.3 share the same basic engine family

If your OBS 7.3 has a belt chirp that keeps coming back, a squeal that shows up at idle, or a habit of wearing belts faster than it should, Ford already had a fix for it. TSB 98-23-14 applies to the 1

The 7.3L Powerstroke is reliable, but it’s not magic. It still has 20-plus-year-old seals, sensors, wiring, filters, and plastic bits trying to survive heat, oil, fuel, vibration, and whoever owned th

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
