Bosch DGK-121 VE Injection pump seal kit.

Case Tractors, Dodge-Cummins Diesel, Onan (Bosch VE - Rotary Style Pumps)

This kit will work for most VE style Bosch Pumps that have a 20MM drive Shaft.

Drive Shaft seal is included for drive shafts 20MM and seal opening in housing 31MM

Many of the pumps run good but leak simple due to o-ring drying out or being effected by the ever-changing diesel fuel chemistry.

We don't recommend tearing your pump apart yourself to install.

3200 RPM spring

This 3200 rpm spring fits all VE Injection pumps on Dodges from 1989 to 1993. The spring will allow the injection pump to fuel all the way to 3200 rpm if you have enough fuel.

No damage will occur to your motor at 3200 rpm, the Cummins 5.9 can be spun to that rpm without issues.
