How to Remove the Fuel Pump From a Pushrod Pontiac 350

The Pontiac 350-cubic-inch V-8 engine is in the same family as the 400- and 455-cubic-inch Pontiac engines. The Pontiac 350 was used until 1977, when it was replaced by the 350-cubic-inch Chevrolet engine. The standard 350 Pontiac engine has a mechanical fuel pump on the driver side of the timing cover, below the water pump. It is driven by an eccentric on the camshaft.

Instructions

1

Park the Pontiac on a level surface and set the parking brake.

2

Place a drain pan under the fuel pump to catch the small amount of fuel that may come out of the lines. Remove the metal fuel line that runs to the carburetor with two line-wrenches. Put one wrench on the fuel pump fitting to hold it and use the other to loosen the fuel line.

3

Loosen the hose clamp on the rubber fuel line from the fuel tank with a flat-head screwdriver. Remove the line and plug it with a 3/8-inch bolt.

4

Remove the two bolts that attach the pump to the timing cover with a ratchet and socket. Remove the pump.

5

Scrape any old gasket material from the mounting surface on the timing cover with a putty knife. Clean the surface with a shop rag and lacquer thinner.

6

Apply gasket sealer to a new pump gasket and press the gasket onto the fuel pump. Apply sealer to the other side of the gasket. Mount the pump on the timing cover. Install the bolts. Use a torque wrench to torque the bolts to 30 foot-pounds. You may have to push the pump against the cover due to pressure on the fuel pump arm, in order to start the bolts.

7

Push the rubber fuel line onto the fitting on the pump and tighten the hose clamp. Start the metal fuel line by hand. Be careful not to cross-thread the fitting. Place a line-wrench on the fuel pump and use another line-wrench to tighten the fuel line.

8

Start the engine and check for leaks.
