Remove Fuel Priming Pump And Filter BaseNOTE: The removal and installation of the fuel priming pump and filler base on the 3408 and 3412 Generator Sets is similar so only one will be shown. In some applications there will be two fuel filters instead of one.
1. Turn the fuel supply valve to the 'OFF' position. Remove two bolts (1), fuel priming pump (2) and the gasket under the fuel priming pump.
2. Use tool (A) to remove fuel filter (3) from the fuel filter base.
3. Put identification on fuel lines (6) for correct installation. Disconnect fuel lines (6). Put plugs and caps over all openings.
4. Remove the bolt that holds clip (5) to the fuel filter base. Remove the other bolt and fuel filter base (4).
5. Remove stud (7) if a replacement is necessary.

2. Install fuel filter base (2) on the engine. Install the bolt that holds clip (3) on the fuel filter base.
3. Connect two fuel lines (4) to the fuel filter base.
4. Put clean diesel fuel on seal (5). Install fuel filter (6) on the fuel filter base. Use tool (A) to tighten the fuel filter 1/2 to 3/4 of a turn more when the seal comes in contact with the fuel filter base.
5. Install the gasket and fuel priming pump (7).
6. Turn the fuel supply valve to the 'ON' position.

EXCERPT:
Individual fuel injection lines carry fuel from the fuel injection pumps to each cylinder. One section of line connects between the fuel injection pump and an adapter on the valve cover base. Another section of line on the inside of the valve cover base connects between the adapter and the fuel injection nozzle (3).
The fuel filters and priming pump are located in a compartment at the front of the fuel tank. The fuel transfer pump is mounted on a drive adapter on the fuel injection pump housing, and is driven by a shaft connected to the fuel injection pump camshaft. Fuel transfer pump relief valve (14) is located in the cover of the pump.
Fuel priming pump (13) is used before the engine is started to put pressure in the fuel system and to vent air from the system. A check valve (9) located in the fuel transfer pump adapter housing will let fuel go around the fuel transfer pump when the priming pump is in use.
There is no bleed orifice or valve installed on the fuel injection pump housing to vent air from this part of the fuel system. Air trapped in the fuel injection lines can be vented by loosening all of the fuel injection line nuts where they connect to the adapters in the valve cover base. Move the governor lever to the low idle position. Crank the engine with the starting motor until fuel without air comes from the fuel line connections. Tighten the fuel line nuts. This procedure is necessary because the fuel priming pump will not give enough pressure to push fuel through the reverse flow check valves in the fuel injection pumps of a direct injection system.
An automatic timing advance unit is mounted on the front of the fuel injection pump camshaft. It is driven by the engine camshaft gear inside the front timing gear housing. The automatic timing advance unit gives easier starting and smooth low speed operation. It will also advance timing as engine speed increases to give correct engine operation efficiency.
