Isuzu diesel / GMC-Isuzu applications using primer pump 16665-99004

Product Overview

A leaking or worn primer can draw air, fail to build pressure or make filter changes difficult because the fuel system cannot be bled properly by hand.

Replacing the primer restores manual fuel movement through the low-pressure side of the system and helps reduce unnecessary starter cranking after service.
