NEW OEM Duramax LB7 Replacement MPROP

NEW OEM Duramax LB7 Replacement Fuel Control Actuator

OEM replacement fuel control actuator. The fuel control actuator (also called FCA, MPROP, Suction control valve, fuel pressure regulator) is a common failure for the Duramax diesel engine. The FCA can cause a check engine light with low fuel pressure codes such as P0087, high fuel pressure codes P0088 and a number of other concerns such as lack of power, surging, smoking, hard start, no start and much more.

The FCA is mounted on the injection pump and is a calculated bleed from the pump to control fuel pressure. It is secured using 3 torx screws and is moderately difficult to install mainly because it's buried in the center of the engine compartment. It's also included on new and re-manufactured Bosch injection pumps.
