The factory 1999–2003 7.3 Powerstroke HPOP lines use quick-connect fittings at the cylinder heads and high-pressure oil pump. They worked, but after more than 20 years of heat, vibration, oil exposure

Summer and the towing season are in full swing. With the temps getting ready to go even higher across the nation, we figured it’s a perfect time to talk about some cooling system components: water pum

The used market has been pretty hot for the last several years. Our old trucks are getting more popular every day! If you’re looking for a new-to-you 7.3, there’s a few things that are worth keeping a

If you’re doing the classic 7.3 Powerstroke 6637/BHAF intake mod, the filter is the whole point: big surface area, less restriction, built for work. The 6637 style has lived forever in the heavy-duty

The Camshaft Position Sensor (CPS) on the 7.3L Powerstroke is a Hall-effect sensor mounted on the front of the engine, positioned just above the harmonic balancer near the 11 o’clock orientation. This

At Riffraff, we stock the PHP Hydra Chip because it fixes the two biggest problems with old-school 7.3 tuning: not knowing what tune you’re on and being stuck with whatever tune was installed years ag

The 7.3L Powerstroke diesel (1994–2003) is widely regarded as one of the most durable diesel truck engines ever produced. Known for its longevity, simplicity, and mechanical reliability, the 7.3 still

Bolt torque for the 6.0 Powerstroke shouldn’t be guesswork. So we pulled the specs from Ford service manuals and other trusted sources, then organized them all in one place below. Consider this your g

The ICP sensor is one of the first things we look at when a 6.0L Powerstroke has a hard start, hot no-start, rough idle, or unexplained surging. ICP stands for Injection Control Pressure. The 6.0L use

The 6.0L Powerstroke has a lot of famous problems, but the EOT/ECT delta is one of the easiest ways to catch trouble before it gets expensive. Bad numbers here can lead to failures across the board. T

A bad-acting 7.3 Powerstroke IPR does not always need to be replaced. Many are simply contaminated with oil debris, varnish, or simply have worn seals. Most replaced IPR failures are really contaminat

Fuel pickup options are everywhere—sumps, draw straws, high-volume pickups, or simply modifying the factory setup. Each solves a specific problem and improves fuel delivery in its own way. But what ac

On a 20+ year old 7.3, the harness usually doesn’t “die” all at once. It fails the annoying way: intermittent faults, weird codes, random driveability issues, and electrical gremlins that disappear th

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

Let’s talk about Powdered Metal Rods, or PMR’s as they’re more commonly called. If there’s one thing that causes the most damage to the 7.3L Powerstroke in one shot, the PMR is it. When these connecti

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

When upgrading a 7.3L Powerstroke (1994–2003) for more power, one of the first hurdles is the PCM’s built-in overboost limit, which is typically around 23–24 PSI. Exceed that, and the system throws a

The 7.3 Powerstroke turbo pedestal is one of the usual suspects when oil shows up in the valley, down the back of the engine, or around the passenger-side up-pipe. On EBPV-equipped trucks, the actuato

Room Temperature Vulcanizing sealant (aka RTV), or any other type of sealant usage is somewhat of a mystery for most of us. It's ok, you don't need to admit it, but we've all been guilty of rolling th

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
