The 1U-6661 Pop Tester Gp 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 1U-6661 Pop Tester Gp to test unit injectors.
Do not use any off-engine diagnostic test on fuel injectors or fuel nozzles prior to installation of the injectors or nozzles. Caterpillar Fuel Systems Division does not recommend the use of any test equipment that is outside of the factory for field evaluation of injectors and nozzles prior to the installation of the injectors or nozzles.
