The fuel pump is a sealed type and is actuated from the engine camshaft. A pushrod is used between the camshaft and the pump rocker. Fuel pumps on 231 V6 engines are driven directly from the camshaft eccentric without pushrod. No servicing can be carried out as the unit is sealed, but if the pump is suspected of being faulty, carry out the following test. Verify that gas is in the
Fuel Tank. Disconnect the primary wire which runs between the coil and the distributor to prevent the engine firing when the starter motor is actuated. (1970-1974 models only).For 1975-1980 models, disconnect the distributor wiring marked 'BAT. Disconnect the fuel inlet pipe from the
Carburetor and place its open end in a container. Operate the starter motor and check that well-defined spurts of fuel are being ejected from the open end of the pipe. If so, the pump is operating correctly; if not. replace the pump as described in the following.
