Fuel System Components for 1988–1994 Ford 7.3L IDI Diesel Trucks

The 7.3L IDI carried over the robust mechanical fuel injection design of the 6.9L, but one problem has persisted through the years — lack of lubricity in modern diesel fuel. Without proper lubrication, injection pumps and injectors can fail prematurely, a challenge that affects even today’s common-rail systems. Thankfully, the aftermarket provides proven solutions to protect and improve your classic Ford diesel’s fuel system.

Start with prevention. Treating every fill-up with Hot Shot’s Secret EDT (Everyday Diesel Treatment) adds critical lubricity, cleans the fuel system, and improves cetane for smoother combustion and more efficient performance. This simple, inexpensive addition helps keep your injection components lubricated and operating at peak condition.

If age and mileage have already taken their toll, stock replacement, no-core injectors are available to restore performance and reliability. These injectors deliver precise fueling and are ready to install right out of the box.

For owners looking to improve filtration beyond the factory system, Glacier Diesel Power’s fuel filtration kit is a great solution. It combines a 10-micron fuel/water separator with a 3-micron secondary filter to ensure your 7.3L IDI is always supplied with clean, water-free diesel. This upgrade protects critical components and helps your engine run smoother for years to come.
