How to Replace a Fuel Pump on a 1970 Pontiac 350

A 1970 Pontiac 350 is a common term for a 1970 Pontiac Firebird with a 350-cubic inch engine. This car used a mechanical fuel pump with a single action diaphragm to deliver fuel to the engine. A push rod between the camshaft and the fuel pump rocker arm operates the fuel pump. The fuel pump in a 1970 Pontiac Firebird is not adjustable or repairable, so you must replace it when it fails.

Instructions

1

Disconnect the fuel intake line and the fuel outlet line from the fuel pump on the lower right side of the engine. Close the open end of the fuel intake line with a clamp.

2

Remove the bolt from the right front mounting boss with a socket wrench. Fill this hole with a longer 3 / 8 inch bolt to hold the push rod for the rocker arm in place.

3

Disconnect the mounting bolts and washers for the fuel pump with a socket wrench. Detach the fuel pump and gasket from the engine.

4

Coat the mating surfaces of the new fuel pump and the engine with sealer. Install the new fuel pump and gasket to the engine, and attach the mounting bolts and washers for the fuel pump.

5

Remove the temporary bolt in the right front mounting boss, and connect the permanent bolt with a socket wrench. Remove the clamp from the fuel intake line, and connect the fuel lines to the fuel pump. Check the fuel system for leaks.
