Diesel engines operate under pressure, which must be within a certain range. That’s where a 7.3 fuel pressure regulator comes in. The truck’s 7.3 Powerstroke fuel pressure regulator ensures that fuel pressure stays within an optimal range as temperatures and other environmental factors change. Eventually, a 7.3 fuel regulator will start to fail, which may lead to misfires or low engine power. +Read more
Replacement is an option, though purchasing a fuel pressure regulator rebuild kit and refurbishing the existing part if you want to vastly extend its lifespan is possible. The IPR valve 7.3 does a similar job, though it focuses on the high-pressure oil the engine uses. Oil is essential for engine lubrication and cooling, so a failed IPR sensor 7.3 or 7.3 IPR valve could ultimately cause catastrophic damage to your vehicle.
If the 7.3 IPR valve is failing, the vehicle may idle roughly, struggle to start, or misfire. You may also hear loud grinding noises from the engine. If you suspect an IPR valve failure don’t drive the vehicle until the part has been checked and replaced if necessary.
