Main Fuel Filter (gasoline)

Because of varying quality of available gasoline, the fuel filter may become clogged enough during normal operation to restrict fuel flow. To prevent any such problems, and to guarantee continued good performance, the filter should be replaced at the specified interval. The man fuel filter is located beneath the car, just in front of the fuel tank as shown in Fig 5-5.

When replacing the fuel filter, disconnect the battery negative (-) terminal and clamp the filter inlet and outlet hoses to lessen fuel spillage. Use new hose clamps. On cars where the inlet and outlet hoses are attached with banjo fittings, torque the inlet fitting to 25 Nm (18 ft. lb.) and the outlet fitting to 20 Nm (15 ft. lb.).

WARNING-

Fuel will be expelled when the filter is removed. Do not smoke or work near heaters or other fire hazards. Keep a fire extinguisher handy.

CAUTION-

Clean thoroughly around the filter connections before removing them, and make sure that no dirt gets into the fuel lines.

CAUTION-

When loosening the fuel filter fittings, always use two wrenches and hold the fuel filter housing by the molded nut. Loosening the fittings alone may twist the filter mounting bracket and damage the plastic fuel reservoir.
