Chevy GM Stanadyne manual injection pump model DB2-4911 completely remanufactured and warranted by SSDiesel Supply^TM, a trusted name in 6.5TD solutions. All wear parts replaced whether they test bad or not, including the head.

Fits all 1992-1993 GM 6.5 Turbo Diesels in C/K pick-ups, Suburbans, G/P van (Express and Savana) and cab/chassis combinations such as school buses with the manual injection pump. Also all Hummer H1's thru 1996 with the manual injection pump.

Compare price only to those remans replacing the head assy with a new upgraded head. Most rebuilders leave the head if test ok and can offer cheaper. We will never cut corners. The head on these pumps has a tendancy to warp with heat and is the #1 source of failure, and if not replaced/upgraded, is just destined to fail. We replace the head everytime with new upgraded Stanadyne heads that solve the warpage problem. A core deposit of $500 will be required, due to the rarity of this pump.

Symptoms of failure include hard starting when hot (common head warpage problem) Poor mileage, rough running, heavy smoke, loss of power.

The manual pump can be easily adjusted for more power with the turn of a screw and an EGT gauge. With purchase, upon request, I will furnish detailed instructions on how to adjust for more power if you already have a 4" exhaust and EGT & Boost gauges.
