Introduction
This Special Instruction contains the necessary procedures and information to prime the fuel system.
Dry Start Priming Procedure
Perform the following procedure to ensure the engine is receiving sufficient fuel to start the engine.
1. Disconnect the fuel return line below (down stream) from the fuel pressure regulator.
2. Install the gauge/valve assembly.
3. Open the valve and use the hand priming pump to fill the engine with fuel.
4. Continue to prime the engine until air is no longer visible in the fuel. Some foam is acceptable (caused by the fuel pressure regulator).
5. Close the valve and use the hand priming pump to increase system pressure to 206 to 275 kPa (30 to 40 psi).
6. Wait approximately eight to ten minutes.
7. Open the valve.
8. Start the engine.
9. If the engine does not start after 2 or 3 attempts, repeat steps 4 through 7.
10. Shut the engine off. Relieve fuel system pressure below (down stream) from the fuel pressure regulator.
11. Remove the gauge/valve assembly and connect the vehicle fuel return line.
