Priming the Fuel System
D24A Diesel Engine Only
In any one of the following cases, the fuel system
requires priming.
Before starting up the engine for the first (priming
completed at factory), exhaust all fuel and refuel
the fuel tank.
After replacing fuel filter or other part of the fuel
system, drained water from oil-water separator, or
after any maintenance work with the fuel system,
perform priming as described below:
Place an approved container under the air bleed
port.
Loosen the hand pump by 2~3 turns until the hand
pump protrudes up (Figure 5-1, (1)).
Press the pump with your hand until the oil comes
out. In this operation, all the fuel hoses must be
connected. (Figure 5-1, (2))
Retighten the hand pump.
Wipe out spilled fuel and dispose of properly.
Never try to crank the engine with the starting
motor to feed the fuel system with fuel. Otherwise,
the starting motor can be overheated and the coil,
pinion, and/or ring gear can be damaged.
