Diesel Fuel & Injection Service

The fuel system is where most serious diesel trouble starts. Modern high-pressure common-rail systems run injectors and pumps at pressures that leave zero room for dirty fuel, water, or air. When something goes wrong here, it goes wrong expensively, so we diagnose and service it before a cheap part takes out a costly one.

Injectors, pumps, and the parts that hurt to replace

A leaking injector can wash down a cylinder. A failing CP pump on a Duramax or Power Stroke can send metal through the entire fuel system. We test injector balance rates, check supply and return pressure, and inspect filtration so we catch the small problem before it becomes a full rail-and-injector job. The earlier we see it, the less it costs you.

Water and contamination kill diesels quietly

Water doesn't lubricate, and these pumps rely on fuel for lubrication. A little water or a single tank of bad fuel can score a pump in short order, and you may not hear a thing until it's too late. If you suspect contamination, stop driving and call us. We'll test, drain, and flush before it spreads through the injectors.

Protect the expensive stuff up front

The cheapest fuel repair is the one you prevent. As an authorized FASS Fuel Systems dealer here in Athens, we can fit your Cummins, Duramax, or Power Stroke with a system that filters finer, separates water, and feeds clean, air-free fuel to the injection system. That's real insurance for the most expensive components on the truck, and it pays for itself the first time it catches a bad tank of fuel.
