7.3 F250 

The 7.3 F250 Power Stroke turbo diesel is characterized by its HEUI (hydraulic electric unit injector) injection system, which uses highly pressurized engine oil as a medium for creating fuel pressure directly in the injector body, as a opposed to a system requiring a typical injector pump. In lieu of an injection pump, the 7.3 F250 Power Stroke utilizes a high pressure oil pump (HPOP). Also a low pressure lift pump in order to create fuel pressures up to 21,000 psi. In comparison to the prior mechanical injection system, the transition to HEUI promised improved performance. The lower emissions, and better fuel economy stemming from increased fuel and greater control over injection events.

The popularity of Ford’s International powered F-Series pickups is distinguishable in its production numbers, which greatly exceeded that of any competing manufacturer’s diesel sales. By 1999, 1 million Power Stroke equipped trucks had been delivered to dealerships. As demand soared following Ford’s introduction of the Super Duty platform, the 2 millionth 7.3 F250 Power Stroke equipped F-Series rolled off the assembly line in 2002. The 7.3 F250 Power Stroke has earned praise as one of the most popular engines offered in a pickup truck. Its name synonymous with reliability and longevity.

7.3 f250 Power Stroke is a line of diesel engines found in Ford Diesel trucks, Ford Excursion SUVs, Ford Econoline vans, Ford LCF commercial vehicles and the Brazilian Ford Ranger. The 7.3 F250 V8 engines were produced by Navistar International Corp. until 2010 when Ford decided to build their diesel engine completely in-house. The Power Stroke engines compete primarily in the United States full-size pickup truck market with the Duramax V8 from General Motors/Isuzu and the B series straight 6 from Cummins.

The 7.3 DI Power Stroke was in production until the second quarter of model year 2003 when it was replaced by the 6.0L because of its inability to meet newer emission requirements. Due to its popularity, nearly 2 million 7.3 F250 were produced from International’s Indianapolis plant.
