HPOP Test Gauge 99-03 7.3L

This gauge allows you to test your HPOP pressure to determine if it is putting out enough pressure to your injectors. We recommend using our IPR block off tool as well to isolate it from a possible faulty IPR regulator. Our gauge allows you to connect to your factory STC HPOP lines for testing. 

*NOTE: If your pump is good and you allow pressure to exceed the gauge pressure limit it may render the gauge unable to be used in the future.
