REMOVAL & INSTALLATION
See Figure 1
The fuel filter on carbureted engines is a plastic cylinder with two ports for the fuel. It is usually located on right rear frame rail, near the fuel tank.
- Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner.
- Grasp the hoses near the ends and twist them gently to pull them free from the filter pipe.
- Pull the filter from the clip and discard.
- Install the new filter into the clip. The arrow must point towards the hose that runs to the carburetor.
- Push the hoses onto the filter pipes, then slide the clamps back into position.
- Start the engine and check for leaks.
See Figures 2, 3 and 4
The fuel filters on injected engines are a metal cylinder which is located in the rear frame rail or in the engine compartment. You may find it under the injection manifold on some models. Each model varies.
- Unbolt the retaining screws and remove the protective shield from the fuel filter.
- Place a pan under the delivery pipe to catch the dripping fuel and SLOWLY loosen the union bolt to bleed off the fuel pressure. The fuel system is under pressure. Release pressure slowly and contain spillage. Observe "''no smoking/no open flame precautions''.
- Remove the union bolt and drain the remaining fuel.
- Disconnect and plug the inlet line.
- Unbolt and remove the fuel filter.
When tightening the fuel line bolts to the fuel filter, you must use a torque wrench. The tightening torque is very important, as under or over tightening may cause fuel leakage. Insure that there is no fuel line interference and that there is sufficient space between the fuel lines and other components.
- Coat the flare unit, union nut and all bolt threads with engine oil.
- Hand-tighten the inlet line to the fuel filter.
- Install the fuel filter and then tighten the inlet line nut to 22 ft. lbs. (29 Nm).
- Reconnect the delivery pipe using new gaskets and then tighten the union bolt to 22 ft. lbs. (29 Nm).
- Run the engine for a short period and check for any fuel leaks.
- Install the protective shield.
