Stanadyne has stopped production on these PMD's and inventory is sold out. We do still have inventory of the Stanadyne PMD & Pump Harness kit #35976. When these are sold out there will be no more gray Stanadyne PMD's available.
Stanadyne is the maker of the GM 6.5L injection pump and has come out with an updated version of the PMD. Stanadyne has termed their new gray or grey colored DS Pump Mounted Driver as "Bullet-Proof", since they incorporated a series of new features for added durability and reliability.
* 2 year warranty is only for PMD's sold after March 25, 2016. PMD's sold before that date only carry a 30 day warranty.
Stanadyne PMD Kit Number 40736 includes new PMD number 39405, heat transfer pad, and four mounting screws. Remote mount cooler and extension harness sold separately.
Note: Since Stanadyne changed the connector between the wiring harness and the PMD, the harness must be changed on the injection pump (supplied with PMD) when installing this PMD.
This Stanadyne PMD kit is the same as the 35976 kit, but without the pump wire harness.
