Swamp's Diesel Performance defines CORE INJECTORS as those injectors which were most recently installed into your vehicle's engine. Injectors returned to us, which are out of a salvage yard, injectors which have been burned, or externally damaged, will NOT be suitable as cores. Any injector which has previously been disassembled will NOT be a suitable core injector. We will not accept injectors as suitable cores that have run waste vegetable oil or alternative fuels (to include home-made veggie or bio fuels).
Your cores will need to meet ALL of the stipulations outlined in our definition of CORE INJECTORS, above, as well as being free of damages which may have occurred due to poor quality fuel being run through the injectors. If your cores have been exposed to gasoline, water, or poor fuel filtration, then you can assume that all 8 of the plunger & barrel assemblies will be damaged, and will need to be replaced at a cost of $480 per set. Normal injector wear, to include poppet valve wear, fuel plate erosion, loss of internal spring tension, etc, is considered normal, and we repair/replace those parts on every set. Normal wear is not something we consider to be out of the ordinary.
Warranty: 5-Year, 200,000 miles (whichever comes first). Our warranty will cover any injector defect caused by our parts (including injector orings), our machining procedures, our assembly and/or testing process, and/or modifications we make to the fuel injector
