The components in this Fuel Injection Test Kit enable the testing of the fuel delivery pressure to the engine. Pressure Gauge (1) connections are made either directly to the pump, or in-line with the pump and engine.
1. Relieve the fuel line pressure from the vehicle fuel system. Refer to the vehicle manufacturer’s service manual for instruction on relieving pressure from the fuel line, testing procedures and connection points, and normal pressure readings.
2. Use the various fittings and hoses to connect the Pressure Gauge (1) directly to the fuel pump, as in the case of the VW®, or in-line with the fuel pump and engine for most other vehicles. See connection examples on the next page.
Use a small amount of pipe compound or teflon tape on the connection threads to prevent leaks. Tighten using a wrench (not supplied).
Caution: Make sure all connections are tight to avoid fuel leaks.
