Stanadyne electronic injection pump latest version model DS4-5521 completely remanufactured and warranted by SSDiesel SupplyTM, a trusted name in 6.5TD solutions. All electronic parts new including the optical sensor.
Fits all 1994-2002 GM 6.5 Turbo Diesels in C/K pick-ups, G/P van (Express and Savana) and cab/chassis combinations such as school buses (except 1994 DS4-5068). And H1 Hummers 1996-2005.
99% of the time, only the PMD fails on these units. If you experience stalling, hesitation, stuttering, poor mileage, or no-start, chances are it is just the PMD failing. Please see our FSD Heat-SyncTM kit ssd-006 which will solve the chronic failure problem associated with PMD's. If you have already tried a new PMD and you are still experiencing problems, the injection pump must be replaced.
Our reman injection pumps feature all the latest upgrades and a 12 month warranty.
Pump is sold less PMD.
Gasket set sold separately, see p/n ssd-5110.
NOTE: THIS PUMP IS SOLD LESS PMD, AS WE DO NOT RECOMMEND THE PMD BEING MOUNTED TO THE PUMP WHERE IT IS DESTINED TO FAIL. Please see our FSD Heat Sync kit p/n ssd-001 if a new PMD is needed.
