2009 ultra classic fuel filter location

Indicates a problem with the fuel pressure. Code could be caused by excessive tank pressure, (loosen fuel cap then tighten). Code may not clear right away. Could also be a plugged fuel filter or a defective fuel pump. Hope this helps.

it is coming from the crankcase vent behind the air filter, some companies offer a kit if it causes a problem for you.

There's probably a sensor in your throttle housing that regulates the amount of fuel that goes through the throttle body to the engine. The sensor could be located on the throttle or you may have a bad throttle body. There are computers on both ends. I believe you ought to call the dealer and find out

my 1999 ultra classic fuel filter is in the tank

the carb must be flooding.
change oil
clean air filter
clean carbs
make sure all the carb hoses are in their original locations. before removing the tank take some notes or photos or number them with correction fluid.
dont leave the fuel tap in the P position, this is for priming the carbs only

The fuel pump is located iside of the fuel tank.

Gas filter on fuel injected models is in the fuel tank attached to the fuel pump. Requires removiing fuel pump from tank to do so.
