My 96, 6.5TD is a new truck after installing these units. Can recommand these for all of you looking for more power & torque. The gear shift improver is also a must to have. Have not tried full power yet, as I want to "break" the engine in step by step....

.DS4-5521 6.5 Fuel Injection Pump

 SSDiesel offers this fully remanufactured electronic injection pump, built by experts in the USA, not some guy on ebay in his garage. All injections pumps are fully rebuilt and upgraded. All wear parts are replaced, whether they test bad or not. Pumps are ultrasonically washed, and reassembled to O.E. specs. After assembly 100% of the pumps are calibrated with application specific test stands designed to simulate all engine conditions, and fully calibrated, so the pump is a simple drop-in for you. Fits all 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.

Beware, there are some unscrupulous rebuilders out there that sell for less. They just clean and re-gasket them and have the nerve to sell as "reman". Our reman injection pumps feature all the latest upgrades and a 12 month warranty. Buy from the name you trust with all your 6.5 needs.
 
Applications: 1996-2005 GM 6.5L Equipped H1 Hummers
Reference Numbers: DS4-5288, 5459, 5521, 5942, 10238969, 12552621, 12561307, 17800077, 12561405, 12558156, 17800114, 19208317, 19208315, 10225930
 
Pump is sold less PMD.
 
*Some 2004 (only) H1 Hummers used an experimental "Cat" ECM and special pump. If an 04, please check the model number of your pump before ordering.

CORE DEPOSIT OF $125 IS REQUIRED

Injection pumps are sold on an exchange basis. Your core must be returned within 30 days.

Gaskets NOT INCLUDED and sold separately, see p/n ssd-306A.

I recommend our Haynes Manual ssd-330 if your first time replacing a pump for the basics. Then if you have any further questions, please contact tech support.

NOTES:

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.

This is a factory order item so you are getting the freshest stock and latest upgrades
