Isuzu / GMC Compatible diesel-engine and equipment applications using the matching primer/filter-head arrangement

Product Overview

A hand primer lets the technician move fuel through the low-pressure side of the system after filter service, a dry tank, line repair, or other work that introduces air. A leaking or non-pumping primer can make bleeding the fuel system unnecessarily difficult.

Cross-reference catalogs connect 16665-99004 with Zexel 152200-5620 and Bosch 9441610017. The pump is used to manually refill and bleed the low-pressure fuel circuit after filter or line service.

Key Features & Performance

  • Manual fuel priming: Provides a convenient way to refill and bleed the low-pressure fuel circuit.
  • Service-time convenience: Useful after filter changes or fuel-system repairs that allow air into the lines.
  • Fitment-specific threads and base: The mounting interface and reference number should match the original primer or filter-head arrangement.

  • Primary Reference: 16665-99004
  • Zexel Reference: 152200-5620

Before You Order

Compare the threaded base, sealing surface and reference number to the original primer. Isuzu/GMC fuel-filter heads can use different primer diameters and thread forms.
