Replacement Procedure
- Locate the fuel filter in the engine compartment. On carbureted models it sits on the fuel line between the tank and carburetor. On fuel-injected 1996+ models it is on the high-pressure side and is typically secured in a bracket.
- Place a rag under the filter to catch spilled fuel. On carbureted trucks you can often just clamp the supply hose with a fuel line pinch clamp to minimize spillage. On FI models, relieve system pressure first by pulling the fuel pump fuse (or relay), cranking the engine briefly until it dies, then turning the key off.
- Note the direction of flow arrow on the old filter before removing it. The new filter must be installed in the same orientation — fuel flows from the tank toward the engine.
- Loosen the hose clamps or banjo bolts and remove the old filter. On banjo-bolt connections, use new copper crush washers on reinstall — the old ones are single-use.
- Install the new filter with the flow arrow pointing toward the engine (carburetor or FI rail).
- Reinstall clamps or banjo bolts. On banjo bolts, torque to spec — typically 20–25 N·m.
- Turn the ignition key to ON (not start) several times to repressurize the system, then inspect for leaks before starting the engine.
Tip:On older trucks with high mileage, the rubber fuel hose connecting to the filter may be brittle or cracked. Replace the short sections of hose at the same time as the filter. Use hose rated for fuel (not generic rubber tubing).
