  Q: How to replace the fuel filter on Chevrolet Astro?

  A:

  For carburetor-equipped vehicles from 1985, the fuel filter is located inside the fuel inlet nut at the carburetor, made of pleated paper or porous bronze, and cannot be cleaned or reused. The procedure should be performed with the engine cold and the engine cover removed, using open-end wrenches for the fuel line nuts and flare nut wrenches if available. Begin by removing the air cleaner assembly, noting or tagging any vacuum hoses that need to be disconnected. Follow the fuel line from the fuel pump to the carburetor, placing rags under the fuel inlet fittings to catch any spilled fuel. Use the proper size wrench to hold the fuel inlet nut while loosening the fitting at the end of the metal fuel line, ensuring the inlet nut remains secure. After disconnecting the fuel line, move it aside without kinking it, then unscrew the fuel inlet nut carefully, taking care not to lose the thin washer-type gasket or the spring behind the fuel filter. Compare the old filter with the new one for length and design, reinstall the spring in the carburetor body, place the new filter in position, and tighten the nut securely without cross-threading. Reconnect the fuel line to the fuel inlet nut, using a back-up wrench to avoid cross-threading. Start the engine and check for leaks, addressing any issues with stripped threads by using thread sealing tape or obtaining a repair kit if necessary. For fuel-injected vehicles, the fuel filter is an in-line type located under the vehicle along the left side frame rail near the engine. Begin by performing the fuel pressure relief procedure, then raise the vehicle securely on jackstands and place a container or rags under the fuel filter. Using two wrenches, disconnect the fuel lines from the filter, and detach the filter from the bracket. Installation is the reverse of removal, ensuring the flow indication arrow on the filter points towards the engine, and check for leaks after starting the engine.
