Dales Super Store - VE Injection Pumps | 1988-1994 Dodge Cummins 5.9L
For the past 21 years, Dodge has offered the B-series Cummins engine in its 3/4- and 1-ton pickups. However, the Bosch-built injection systems found on these straight-six diesels have varied greatly throughout the years. The '89 to '93 trucks featured a mechanical-injection distributor-type pump (VE rotary) that has been proven reliable but is thought to offer the least horsepower potential.
The VE injection pump is a mechanically controlled, axial-piston rotary pump. It uses a vane-type supply pump to generate an internal pump pressure that increases with engine speed and has a single pumping plunger called a distributor plunger. This plunging and rotating shaft generates injection pressure and controls injection timing. Six individual delivery valves, located in the pump body, connect the pump to the injectors. It can be fitted with many options to aid in starting, atmospheric pressure compensation, manifold pressure compensation, and temperature-controlled idle speed increase.
