Fuel Filter: Testing and Inspection

Assembling Advice
By applying engine oil or light oil to the pipe, port makes pipe assembly easier. The pipe assembly should take place immediately after applying oil (to prevent dust from sticking to the pipe surface - which may decrease sealing ability).

Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the "ON" position and listen for pump start-up sound. Inspect for leaks, the fuel pressure will increase as the fuel pump is actuated.
3. Perform leak inspection (step 2) several times.
4. Start the engine and observe the engine idle speed. The presence of dirt in the fuel system may affect the fuel injection system.

Inspection
After installation, start engine and check for fuel leakage.
