Silverado Fuel Filter

Removal Procedure

1. Disconnect the negative battery cable from the battery and place it in a safe location where it will not have a chance to come in contact with the battery.

2. Loosen the gas cap to relieve the gas tank of any vapor pressure.

3. Locate the fuel pressure regulator on the driver’s side fuel rail.

4. Take your pressure gauge and place the bleed hose into your catch can/pan. Consider taping the hose to the wall of the container to lessen the chance of getting fuel in unwanted areas.

5. Take your towel and wrap it around the pressure valve to catch any leaked fuel, and drain any remaining fuel within the gauge into your catch can/pan.

6. Lift your Silverado with your floor jack and place it securely on jack stands.

7. Locate the fuel filter along the inside of the driver’s side frame rail, and clean the connection to the filter with a towel.

8. Disconnect the fuel lines and threaded fitting from the fuel filter. It’s recommended to loosen the clamps on the fuel lines that are before and after the filter for easy removal.

Notice: You will need two wrenches to work opposite of one another to release the fittings holding the metal fuel line to the filter.

9. Once the filter is loose, slide it off of the mounting bracket on the frame rail. Once the lines are disconnected, cover them to prevent any contaminants from entering the lines.

Notice: The metal fuel lines will bend a bit, but be sure not to kink them. Have your catch can/pan ready as the filter holds up to five ounces of fuel.

Installation Procedure

1. Before installing the new fuel filter, inspect the fuel line O-rings to ensure they’re free of any damage or distortion. If you find any signs of damage, replace them.

2. Slip the new filter onto the bracket, ensure it is facing the same direction as the fuel flow, and connect the threaded fittings to the filter.

Notice: Tighten the fittings to 18 ft/lbs.

3. Lower your Silverado down off of the jack stands, fill the gas tank, and tighten the gas cap.

4. Reconnect the negative battery cable to the battery.

5. Turn your Silverado’s ignition on for two seconds, then turn it off for 10 seconds, then turn it back on. This restores your fuel system’s pressure levels.

6. Leave your Silverado running and check for any leaks.

That’s it, you’re all done!
