The Ford 7.3L PowerStroke diesel engine has legendary reliability, but since these trucks are around 20 years old and most of them have 200,000 miles or more, a few repair bills here and there are to be expected. One of the more common repairs on these trucks is diesel fuel injector replacement. These were the first pickup trucks available in the US with direct injection, where fuel was metered out at each individual injector rather than from a centralized injection pump. This allows for better fuel control, which leads to better performance and decreased emissions, but that also means each injector is significantly more complicated, with many more moving parts. As the trucks age, the biggest issue with injectors is their propensity to start leaking. They also have an electronic component that can see wear over time from being in such a heated area under the hood.
When it comes time to replace the injectors on your 7.3, the choices can be overwhelming. Different years had some minor differences in the injector design, and there are multiple varieties of each design available; brand new, remanufactured, OEM or aftermarket. The main varieties of PowerStroke injectors are broken down by model and year:
1994-1998 “Old Body Style” trucks, 1994-1996 E-Series Van
The 7.3L PowerStroke diesel in these trucks was offered at the same time as the older 7.3L IDI diesel, but despite having the same displacement, they do not share any parts at all, so make sure to keep that in mind when ordering anything. To tell the difference, Powerstroke OBS trucks will have a PowerStroke logo under the F-250 or F-350 badge on the fenders. These were also the first trucks to use the “Super Duty” name.
Early 1999 Super Duty, 1997-Early 1999 E-Series Van
These are the first Super Duty trucks with a design substantially different from the standard F-150. There technically is no model year 1998 Super Duty, but 1999 models were on dealer lots in the spring of 1998, which may have caused some confusion at the time. These injectors are a one-year-only model; Ford made some revisions in December of 1998, and these are for models produced before then. Early 1999 trucks can be spotted by PowerStroke badges on the fenders, while later trucks have them on the doors.
Late 1999-2003 Super Duty, Excursion and E-Series Van
This is the most common 7.3 injector, since it had the longest production run. This is for trucks built December 1998 and later; the PowerStroke badges will be on the doors rather than fenders. The #8 cylinder has a slightly longer nozzle, but the 7 others will all be identical. These are also the injectors found in all 7.3L Diesel Excursions.
We offer both brand new aftermarket and remanufactured OEM diesel injectors for all PowerStroke applications, depending on what you prefer. Our remanufactured injectors reuse OEM housings, so you can be sure they’ll fit perfectly because they’ve already lived an entire life in a truck much like your own. All wear items and seals are replaced, and the electrical components are all cleaned to ensure perfect contact. We also offer brand new aftermarket injectors that do not utilize any used components. These are our own brand, which we manufacture, and they’re guaranteed to fit and perform exactly the same as a brand new OEM injector, which would cost double or more at a dealership. Different customers have different preferences, so we offer both options. All our diesel injection components are backed by a one year, unlimited mileage warranty, with extended warranty options available. We also offer free shipping, plus free return shipping for your core return if you order our remanufactured units.
