1. When the priming pump is not used, the position of fuel line and plug are reversed. Some of the fuel in the manifold is sent back through the anti-siphon block and through the return line to the fuel tank to remove air from the system after the fuel filter is changed.Orifices in the anti-siphon block control the amount of fuel that goes back to the fuel tank.2. If the engine does not start, the injection pumps and high pressure lines must be primed.Injection Pumps and Lines
The injection pumps and high pressure lines must be primed if the engine will not start or runs rough.Each injection pump has a reverse flow check valve. Use the following procedure to prime the injection pumps and lines.
The fuel injection lines, adapters and/or nozzles can be permanently damaged by twisting if only one wrench is used to loosen or tighten the fuel line nuts. Use one wrench to hold the nozzle and/or adapter, and another to loosen the nut.
1. Loosen each of the fuel line nuts at the cylinder head end.2. Crank the engine with the starting motor until fuel flows, free of air bubbles, from each of the injection lines. Stop cranking the engine.
Do not crank the engine for more than 30 seconds. Allow 2 minutes for the starter to cool before cranking again.
3. Tighten each of the fuel line nuts to a torque of 41 + 7 N m (30 + 5 lb ft). Use a second wrench on the nozzle and/or adapter.4. Start the engine and check for leaks.
