Your fuel injected Harley Davidson touring bike needs a proper supply of presureized fuel to run properly. And much like air filters cleanse the air as it enters the engine, fuel filters strain any unwanted contaminants from the fuel before it is plumbed to the fuel injection system. While modern gasoline is highly refined and quite clean, occasionally contaminants do get into the tank and get stopped by the fuel filter element.

The filter can become clogged, and the pump has to work harder when that happens, which can cause premature failure. Many ridebility issues and a general lack of engine performance can be linked back to a dirty fuel filter, so Harley-Davidson recommends replacing it at teplace, mile intervals.

Learn more Changing the fuel filter is a part of regular maintenance.

Keeping your fuel system properly maintained by changing the fuel filter prolongs the life of the fuel pump. Dirt in the fuel is captured by the filter which clogs over time, causing it to operate less efficiently.

The clogged filter reduces fuel pressure and volume in the fuel system. If your vehicle is losing power, it could be a sign of a clogged fuel filter. Note: This guide applies to gasoline engine vehicles only. The fuel filters in diesel cars and trucks are usually much larger, and the whole fuel system is much more complex.

Diesel engine fuel systems are also under a lot more pressure, with modern common rail systems producing over bar of pressure.

Accidentally releasing such high pressure could result in injury. Then, use a flathead screwdriver to pop out the plastic clips holding the fuel filter in place. Next, slide the fuel lines away from the filter so you can take them off the nozzles on either end. You can then slide the old fuel filter out of its bracket.

Part 1 of In order to relieve the pressure in your fuel system, you will need to run the vehicle without the fuel pump functioning for a short time. In order to prevent the fuel pump from turning on with the engine, you will need to locate the fuse box that contains the fuel pump fuse.

Most vehicles have a fuse box both in the interior of the car as well as under the hood. The fuse for the fuel pump is often in the fuse box locating in the interior of the vehicle. Remove the fuse for the fuel pump. Use a pair of needle nose pliers or plastic tweezers to remove the fuse.

There is still fuel and pressure in the fuel lines running from the rear to the front of the vehicle. Ensure the vehicle is not in gear. Although the engine will not be receiving a fresh supply of fuel from the gas tank, there will be enough fuel left in the lines for it to start and run briefly.

Make sure automatic vehicles are in park and vehicles equipped with a standard transmission are in neutral with the parking brake engaged. Be sure the parking brake is engaged if you are in a standard vehicle. The parking brake is optional but advised for automatics. Start the engine. Insert the key into the ignition and turn it to start the motor just as you would any other time. The engine should start easily as it expends the fuel remaining in the fuel system past the fuel pump.

If the engine dies, the fuel pressure will be sufficiently relieved. Allow the engine to run for a minute before shutting it off. Depending on the fuel system in your vehicle and its average fuel consumption, the amount of time it will run without a functioning fuel pump can vary greatly.

It does not need to run until it dies, however. Instead just allow it to run for a minute or two before turning the key back to off. Allowing the engine to run until it dies may make it difficult to start it again. Re-insert the fuel pump fuse. With the pressure relieved from the fuel system and the engine off, you can re-insert the fuse that powers the fuel pump. Place the cover back on the fuse box and return any pieces of the trim you may have needed to remove to access it.

Do not start the engine again after inserting the fuel pump fuse. Part 2 of Disconnect the battery. Now that there is no reason for the engine to be started again until the project is complete, you should disconnect the negative terminal on the battery. Removing the cable from the negative terminal will prevent the engine from being started while you work.

You will need to use a hand or socket wrench to loosen the nut holding the cable onto the negative terminal, but you will not need to remove the nut completely. Locate the fuel filter. The most common location for modern vehicles is along the fuel line on the bottom of the car, just past the fuel pump. In some vehicles, the fuel filter is located in the engine bay on the line that leads to the fuel rail.

You may need to access the fuel filter from inside the cabin of some vehicles. Jack up the car if necessary. If the fuel filter is located on the underside of your vehicle, you will need to jack up the car to access it.

Slide the jack under the car at one of its designated jack points, then either pump or twist the handle to raise the vehicle depending on the style of jack. Never rely on a jack to support the weight of a vehicle you are beneath while working.

Place a bowl or bucket beneath the fuel filter. Although you relieved the pressure in the fuel line, there may be a bit of fuel left in the line that can spill out when disconnected from the fuel filter. Place a bowl or bucket beneath the fuel filter to catch any fuel that drips or pours out.

Gasoline should be held in its own container until it can be dropped off to a recycling location. Be careful of using plastic containers to hold gas, as it may eat through some kinds of plastic and cause a leak.

Remove the clips holding the fuel filter in place. Most fuel filters are held in place by two plastic clips. Locate the clips on either side of the cylindrical fuel filter, then use a flat head screwdriver to pop them out of the holes they are in. These clips may break as you remove them, so purchasing replacement clips along with your fuel filter is advised.

If you are able to remove them without them breaking, they may be reused. You can purchase replacement fuel filter clips at your local auto parts store. Remove the fuel lines from the filter. With the clips removed, slide the fuel lines away from the filter to pop them off of the nozzles on either end. Make sure to tip the fuel lines toward the bowl or bucket in place as you remove them to catch any spilled gasoline.

Do your best to avoid allowing any gas to pour out onto the ground. Slide the fuel filter out of its bracket. The fuel filter is likely held in place by a metal bracket that wraps around its outer housing. With the fuel lines disconnected, you can slide the fuel filter out of the bracket by pushing it toward the front of the car.

The fuel filter will have a slight bell shape, allowing it to slide out in only one direction. Some fuel filters under the hood may he held in the bracket with a bolt that will need to be removed to slide the filter out. Part 3 of Compare the new filter to the old one. Before installing the new fuel filter, compare it to the one you just removed. Make sure they appear to be the same outside diameter, that the nozzles are the same size, and that it will fit into the bracket.

Do not attempt to use a fuel filter for a different application in your vehicle, as it may not be capable of allowing the appropriate volume of fuel to pass through it. Slide the new fuel filter into the bracket. The new fuel filter should easily slide into its bracket.

If you have to force it, it is likely not the correct diameter.
