*Fuel injectors are sold in sets of 8. Call for single fuel injector pricing. We use ONLY New Alliant Power External O-rings, beware of cheap o-rings. We have had multiple customers call us with competitor products using inferior o-rings that have failed.
Core charge will be refunded provided your existing Powerstroke injectors do not have any external damage and are rebuildable.
Under no circumstances will any injector cores be accepted that are shipped via United States Postal Service. There is a $50 per day late fee for cores returned after 21 days. Cores must be injectors that are in good physical condition, are rust free, and have not been burned or externally damaged. Cores that have been subjected to any alternative or "Bio" fuels will not be accepted as good cores. Any injector received that is disassembled or missing parts will not be accepted as a good core. There is a $50.00 charge per damaged solenoid. Cores should be returned in original packaging to avoid damage. To make special arrangements for core returns please contact us for approval.
