Chevrolet 25055083 Filter Pkg, Fuel

The fuel filter is behind the fuel inlet on the carburetor. Next, disconnect the fuel line from the filter nut, remove the nut, and the filter and spring. For fuel-injected engines, the filters are on the frame rails or rear cross member. Then, depressurize the fuel system, disconnect the battery cable, and remove the filter and O-rings.

To begin, relieve the fuel system pressure. Fuel injected models have a stainless steel in-line fuel filter, which is located at the left rear of the engine on TBI engines and attached to the cylinder head. On MPFI engines, the fuel filter is connected to the frame rail or rear crossmember near the fuel tank. With the engine cold, place a container or rags under the filter. Remove the lines from the ends of the filter, then take out the attaching bolts and separate the filter. Install the new filter, ensuring it is facing the correct direction. Finally, reverse the steps for installation.

On carbureted models, the fuel filter is located inside the fuel inlet at the carburetor and is made of pleated paper that cannot be cleaned or reused. This job should be done with the engine cold, using open-end wrenches to fit the fuel line nuts and a replacement filter. The air cleaner assembly should be removed, and the fuel line located where it enters the carburetor. Rags should be placed under the fuel inlet fittings to catch spilled fuel, and the fuel line fitting should be loosened with a flare nut wrench. After the fuel line is disconnected, the fuel inlet filter nut can be unscrewed, being careful not to lose the thin washer-type gasket or the spring located behind the fuel filter. The old filter should be compared with the new one before installation. The new filter is placed in position behind the spring, with a rubber gasket and check valve at one end pointing away from the carburetor. A new washer-type gasket is installed on the fuel inlet filter nut and tightened securely. The fuel line is then reconnected, and the engine started to check for leaks. If leaks are found, the fuel line connector should be disconnected and checked for stripped or damaged threads. The air cleaner assembly is then reinstalled. Fuel-injected engines employ a stainless steel in-line fuel filter, located at various positions depending on the engine model. With the engine cold, a container is placed under the fuel filter, and the fuel lines are disconnected from each side of the filter. The fuel filter bracket is then removed, and a new filter installed. The fittings are tightened securely, and the ignition key turned on to check for leaks.

In order to separate the fuel line from the carburetor, loosen this connection at the fuel inlet nut. Once you have taken out the fuel inlet nut from your carb, remove this spring and filter. The hole end of the filter should face towards the fuel inlet nut when returning back together with the spring and filter. A fresh gasket must be put on its carb-fuel-inlet-nut before screwing it in place. Lastly, position a wrench with respect to an appropriate torque for a fuel line and lightening connector.
