Truck Engine News SEBD6654, 31 May 1994, "Changes to Unit Injector Test Procedures and Specification". Disregard the article. Refer to the information below.

The 6V-4022 Fuel Injector Tester was cancelled and replaced by components that were also cancelled or discontinued. The tester was rendered obsolete by increased injection pressures and by performance requirements for injectors.

Do not use the 6V-4022 Fuel Injector Tester to test unit injectors.
