1996-2003 7.3L 17 degree HPOP with new gasket. Comes standard with steel inserts. Upgraded above factory 15 degree HPOP. Each pump is flow tested to eliminate DOA pump issues. Very beneficial upgrade to replace worn high mileage HPOPS. Also, huge benefits with having tuning or upgraded injectors to be supported better. Recommend this pump up to 200cc injectors or lower. Most factory injectors are 140cc. SO!! THis pump will defiantly maintain above OEM Injector size. Free return shipping label provided for core exchange in the lower 48 states. Refundable Core charge is $275. Will be refunded when core is received. Will have 30 days to return the core. If not returned core charge fee WILL NOT be refunded.
