Priming the fuel system after fuel filter
change (Using J-47912 priming can)
1. Ensure priming canister is ¾ full (approximately
9 liters) of fuel.
2. Install fuel priming canister to the priming
port on the fuel filter module.
3. Ensure priming canister shutoff valve is closed.
4. Pressurize priming canister to maximum
5. Open shutoff valve and allow system to fill
for 60 seconds.
6. Close shut off valve.
7. Check for fuel leaks, repair as necessary.
8. Crank engine for no more than 20 seconds.
9. If the engine starts, go to step12.
10. If engine does not start, allow for a 60-second
cool-down and repeat steps 4-8. The starting
cycle can be repeated up to three times.
11. If engine still fails to start:
[a] Use DDDL to check for fault codes.
Repair as necessary.
[b] Repeat steps 4 through 9.
12. Remove priming canister from filter module.
13. Allow engine to reach operating temperature
60°C (140°F).
14. Increase engine speed to 1800 RPM for
three minutes.
15. Reduce RPM and check for fuel leaks or
service codes. Repair or clear if necessary.
Leaving the hose connected with the engine running will cause the holding tank to overfill.
