Venting of the fuel oil system
If the fuel in the tank is used up, it is likely that air has been sucked into the fu 鄄
el oil system. If it is the case, fuel oil will not be able to get sucked into the en 鄄
gine. To prevent such phenomenon, venting must be done for the fuel oil sys 鄄
tem.
For venting of the HFC4DA1 series diesel engine, loosen the nut of high pres
鄄
sure pipe of Cylinder 4, use the starter to start the engine for about 10 seconds
before tighten the nut.
1. Press up and down the handle of the manual oil pump fixed on the oil/water
separator for several times, to lead the fuel containing air from the fuel oil sys
鄄
tem into the jet pump.
2. After the venting of the fuel oil system is finished, start the engine with the
start switch.
3. If the engine fails to start within 10 seconds, then repeat Step 1 and 2.
