The replaceable fuel filter is located in the fuel line, either mounted on the firewall under the hood or located at the rear of the car near the tank.
The filter should be inspected for external damage and/or leakage at least once a year; it should be changed at the proper intervals or more often under dry, dusty conditions.
Removal and installation procedures differ slightly for each year and application.
REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4Carbureted Engines
- Disconnect the negative battery cable.
- Remove the gas hose clamps from the inlet and outlet hoses.
- Work the hoses off (contain spillage) of the fuel filter necks.
- Snap the filter out of its bracket and replace it with a new one. Replace the gas line hose or clamps as necessary.
The arrow on the fuel filter MUST always point toward the carburetor.
- Installation of the remaining components is in the reverse order of removal. Run the engine for a few minutes and check the fuel filter for any leaks.
- Disconnect the negative battery cable. Unbolt the retaining screws and remove the protective shield for the fuel filter (if so equipped).
- Place a pan under the delivery pipe (large connection) to catch the dripping fuel and SLOWLY loosen the union bolt to bleed off the fuel pressure.
- 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 union bolts to the fuel filter, you must use a torque wrench. Use a crow's foot wrench attachment when tightening the fittings. 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 clearance between it and any other parts.
- Lightly coat the flare nut, union nut and bolt threads with engine oil.
- hand-tighten the inlet line to the fuel filter.
- Install the fuel filter and then tighten the inlet bolt to 22 ft. lbs. (30 Nm).
- Reconnect the delivery pipe using new gaskets and then tighten the union bolt to 22 ft. lbs. (30 Nm).
- Run the engine for a few minutes and check for any fuel leaks.
- Install the protective shield (if so equipped).
