Hi Anonymous, if you have a carburator the fuel filter is on top of the fuel valve. If you are injected, depending on your year and model, the fuel filter is either connected to the pressure regulator on early models or has it's own housing that the pressure regulator fits into and clips to the top plate of the fuel tank late models. Good luck

SOURCE: fuel gage not working on harley fat boy

The fuel gauge is really two parts. You have a guage and a sending unit. You must have voltage going to the unit as well. On most models, the wires that supply voltage to the gauge run upwards through a small tube in the tank for the bottom of the tank. There is a connector at the bottom of the tank in most cases.

Using a VOM (volt/ohm meter) unplug the connector beneath the tank and check for voltage with the ignition switch on. You should have approx. 12 volts. Once you've finished this test, turn the switch back to the off position.

Next, you will have to check the sending unit. Remove the gauge from it's rubber gasket that holds it in position on the tank. Carefully work the gauge up and out of the rubber sleeve because the wires are very short. Once you have the gauge out, you'll have to check the resistance of the sending unit with the tank nearly full and then again with the tank nearly empty. If the resistance of the sending unit changes, the problem is probably the gauge itself. If the resistance does not change, the problem is more than likely with the sending unit. Check the sending unit for a good ground as well.

The sending unit is held in the tank by five or six small screws. Remove these screws and lift the unit slightly. Do not attempt to remove the sending unit with the fuel tanks full and the bike on the side stand. Fuel will be all the way to the top of the tank and will spill out when you attempt to remove the sending unit. While lifting the unit, turn it working the float arm out of the tank. Be very careful not to bend the float arm. Once you have the unit out of the tank, you can check the unit's resistance again. When you remove the sending unit, always replace the gasket that goes beneath the unit.

Be very careful, you are working with gasoline and expolsive fumes. Do not smoke or have any open flames near.

SOURCE: Want to replace rear brake pads 1995 Harley Fat boy

Replacing the pads on your Fat Boy is not difficult but you need to pay close attention to the way things are put together as you take it apart. Particularly the little steel pad retainers and the anti-rattle spring. These parts are made and go together in such a way that it's very hard to describe how they go in.

To remove the pads, take the two caliper retaining bolts out of the disc brake caliper. These are usually Torx head bolts. Once you get the bolts out, the caliper simply slides to the front and off of the pads. You'll need a way to push the piston back into the caliper so it will go down onto the new pads. I usually do this with a large pair of slip joint pliers. Make sure you put a rag or something on your calipers so you don't damage the piston or the paint.

Now, look at the way the pads, the little steel pieces at each end of the pads and the anti-rattle spring are in the caliper support bracket. Remove the old pads and parts and install the new pads and parts in the same way. Make sure you put the fiber face of the pad TOWARDS THE ROTOR. Don't laugh, I've lots of people put them in backwards, especially on the back side of the rotor.

Now, carefully slide the caliper back down over the pads taking care not to knock the pads out of there positions. I put a little Loctite 242 (med. strength blue) on the threads of the caliper retainer bolts and reinstall them. Torque them to about 25 foot pounds.
Check the brake fluid level in the rear master cylinder and slowly "pump" the rear brake pedal until the rear brake feels firm. Wait a few minutes and mash the brake pedal one time to the bottom. If it goes down to lower point and then on the next "pump" is higher, you probably need to bleed air from the system.

Open the bleeder valve on the caliper, press the rear brake pedal to the bottom and hold it there, close the bleed valve, and then release the brake pedal. Continue to do this until all the air is out of the system and the rear brake pedal feels firm on the first time it's depressed. While doing this, never allow the rear brake fluid reserviour to run out of fluid. If it does, you'll have to start all over with the bleeding process. Use only DOT 5 brake fluid. DOT 5 and DOT 3 or 4 are NOT compatible and will not mix. If they are mixed, it will cause you a lot of trouble in the future.

Test the brakes before you ride the bike and then again when you first ride the bike at a very low speed. Failure to do this job properly can cause serious injury or death. Brakes must operate properly. Good Luck!

SOURCE: 99 Harley FLHTCU EFI, engine occasionally dies, on

Sometimes there is adaquate pressure and we don't hear the pump, but it does pump while crank and running. A couple of things here, one is the fuel filter, etc. and battery. You did not say how many miles are on the bie, somethings like the fuel filter are usually replaced based on mileage; while depending whee you are 3 years on a battery is about all you can expect.
The reasons why the bike dies can be many, especially at low RPM or idle. Check your air filter, replace if needed. Change your plugs if they are questionable. Change your fuel filter if you have 40K miles on the bike. Unfortunately you could have a range of sensors that are "tired" or about to go bad if the problem persist. The easiest thing to do is take to your dealer if after changing plugs, fuel filter, and air cleaner doesn't help. The dealer will hace the specialty tools to test the sensors and other components that may be in question. Usually they can determine what needs to be done in less than an hour.
Hope this helps.

Is it coming from the inside of the connector or between the connector and the tank? If its between tank and connector its an O-ring issue. If its internal of the connector you will need to replace the whole Connector.

What is the difference between a 2005 efi gas tank and a carburetor model


I believe all 2005 Fat Boys were EFI and no production models w/carb. Generally, the difference between an EFI tank and carb tank is that the EFI has a fuel return port. If you look at the left side bottom you will see what appears to be two fuel lines. One is supply and the other is return from the fuel pump. I believe 1999 was last year of carbed Fat Boys. Left side tank has only one fuel supply port.
