I am having problems removing the fuel filter from the fuel harness and from the backside of the fuel pump that attaches to the back of the tank on my 2006 Polaris 700 RMK? Is there a special tool or technique to remove the filter and the other fuel line from the pump? I have to replace my fuel pump and filter as the plastic fuel line literally desentegrated inside the tank. Any ideas would be great. Also is there a trick to getting the fuel pump assembly and float back into the tank without the float falling off while placing assemly inside the tank? Any ideas would be helpful. Thanks
