How’s it going everybody? Landan with Late Model Restoration. In this installment of LMR Basics, I’m going to be showing you the general steps on replacing your fuel filter and will be doing the work on this ninety coupe.

The fuel filter plays a vital role in your Mustang’s fuel system. Unfiltered fuel contains dirt and debris which cause pre-mature failure to other fuel related components such as lines and injectors. Replacing the fuel pump is something you should do fairly often. In most cases, Ford recommends every thirty thousand miles on applicable vehicles.

This task is very easy compared to others and can be completed in little to no time at all. You’ll of course need a few supplies to tackle this job such as a pair of safety glasses, gloves, a socket set, flat head screwdriver, rags, and a drain pan to catch any fuel that may run out of the lines or old filter.

To begin, pop the hood and disconnect the negative battery cable. Locate the Schrader valve and unscrew the protective cap. Use a flat head screw driver to depress the valve so that it bleeds the fuel system pressure. Of course, have a few rags ready to catch any fuel that may run out.

When that’s done, reinstall the protective cap and then support the vehicle via a lift or jack stands. Position the drain pan underneath the fuel filter. Use a flat head screwdriver to pry the plastic clip out of the line connecter.

Have a rag ready and disconnect the line from the filter. Be ready to catch any fuel that runs out.

Repeat these steps for the other connection.

Once the lines are free from the filter, loosen the clamp with an 8mm socket. Have a rag ready and then carefully slide the filter out of the bracket. Take this time to wipe up any excess fuel and lightly clean the area.

Take your new filter and make sure you install it with the arrow facing toward the driver side of the car. Slide it into the bracket and retighten the clamp. Position the lines on the new filter and then use the provided clips to secure them in place.
Double check your work, reconnect the negative battery cable and you’re all finished.


Installation time will obviously vary depending on the individual, but shouldn’t take you no more than forty-five minutes from start to finish. After I took the old filter out of the car, I slammed it on the ground a few times to demonstrate what the media catches in a filter. As you can see, it’s fairly disgusting and this is why you want to maintain your fuel system properly.
