Fuel Filter


Never smoke when working around gasoline! Avoid all sources of sparks or ignition. Gasoline vapors are EXTREMELY volatile!

Fig. Fig. 1: Example of the cartridge type fuel filter

Some 1967-78 models had a cartridge type filter enclosed in a canister located in the fuel line. To replace the filter, unscrew the body of the canister, discard the gasoline safely and install a new cartridge. Screw the canister body on securely.

On some 1967-78 and all carbureted models thereafter, the fuel filter is a disposable type sealed paper element located in the fuel line.

On 1967 models, the filter is located in the line just before it enters the carburetor. In all other years, it is located in the line near the fuel pump. Later models also have another filter located on the fuel tank in the end of the fuel suction tube. This filter does not normally require service, although it is replaceable.

To replace the filter, remove the two hose clamps and discard the old filter. Install a new filter in the line and attach with new clamps.

Position a container to catch any spilled fuel.

The fuel filter is located inline on the inside of the left frame rail just ahead of the crossmember. To change the filter:

  1. Relieve the fuel system pressure as described in Fuel System .
  3. Remove the filter retaining screw and remove the filter from the frame rail.
  5. Loosen the fuel hose clamps, wrap a shop towel around the hoses and disconnect the hoses from the filter.
  7. Installation is the reverse of removal. Tighten the filter mounting screw to 75 inch lbs.

Fig. Fig. 6: Cutaway view of the diesel inline fuel filter

A gauze filter, located at the inlet port of the fuel feed pump, is designed to catch large particles of dirt in the fuel line. This filter must be cleaned every 12,000 miles in kerosene.

Another in-line fuel filter must be inspected every 12,000 miles. Loosen the drain plug at the bottom of the filter and drain the fuel. Loosen the case attaching bolt and detach the filter case from the cover. Replace the element if it appears dirty or clogged, or at least every 24,000 miles.
