Product Overview

A hand primer allows the technician to refill the low-pressure fuel circuit and purge air after fuel-filter changes, running the tank dry or opening fuel lines. A leaking or seized primer can make bleeding difficult and can also become an air-entry point in the fuel system.

Cross-reference data ties this primer to Komatsu 4D95L-1FF/1GG applications and several Isuzu industrial engines, including 4BC2, 4BE1, 4BG1 and 4JG1. The listing includes two primer pumps.

Frequently Asked Questions

Q: What is the hand primer used for?
A: It manually moves fuel and air through the low-pressure side so the system can be bled after service.

Q: Can a leaking primer cause hard starting?
A: Yes. A worn primer seal can allow air into the fuel supply and contribute to loss of prime.

Compare thread/mounting details and feed-pump application with the original primer.
