The engine in your 1993 Chevrolet Caprice comes equipped with a throttle body injection (TBI) system that automatically depressurizes the fuel system whenever you turn off the ignition. This makes it relatively easy to replace the fuel filter on your Caprice. Best of all, you can perform this task in about an hour with a few simple tools you might already have in your toolbox. However, make sure to install the filter in the direction of fuel flow to avoid starving your engine during operation.
Tools Used: Tools, Wrench, Floor jack, Jack stand, Chocks (2), Shop rags, Ratchet, Socket, New engine oil
Change the Fuel Filter
Removing the fuel filter – Park your Caprice on level ground. Detach the black ground battery cable using a wrench. Release the parking brake and set the transmission to neutral.
Lift the rear passenger’s side wheel/tire assembly using a floor jack and support the caron a jack stand. Chock both front wheels. Locate the filter on the frame rail — passenger side, right in front of the rear wheel axle.
Clean the fuel lines and fittings on both sides of the fuel filter using a shop rag to keep dirt from getting into the lines once disconnected. Wrap a shop rag around one of the fuel lines.
