Equipped with a hydraulic electronic unit injector system, Ford’s 7.3 Powerstroke combined a high-pressure oil pump (HPOP) and a low-pressure lift pump to deliver up to 21,000 psi in fuel pressure. Compared to an injector pump setup, this injection system offered better performance and fuel economy, as well as lower emissions.

While the 7.3 is known as perhaps the most reliable Powerstroke engine ever produced, it wasn’t free of fuel system troubles. The 7.3 Powerstroke fuel lines or a cracked filter housing can leak. A common issue with the 7.3 is the heater element in the bottom of the fuel bowl. The fuel bowl heater can short out and cause the maxi fuse to blow, disabling the power control module.
