Pump and controller

Bosch describes VP44 as a diesel distributor injection pump. In its PSG16 arrangement, the electronic control unit is mounted directly on the pump and combines engine and pump control functions. The pump assembly and controller are related but distinct hardware; VP44 alone is not a complete controller or part-number identification.

The catalogue records VP44 PSG16 and places it in the Bosch fuel-pump group. Confirm the exact pump and controller identifiers for an application.

The catalogue also retains a separate PSG16 identity and a generic VE pump record in the fuel-pump group. Bosch describes VE distributor pumps with mechanical or electronic governing, so VE alone does not identify a particular ECU.
