500 Sportsman- ready to change fuel pump?
I have tore apart the fareings to access the fuel tank on my 2005 500 sportsman EFI.
I have discussed on another thread to get the replacement fuel pump, but had a question----
I tested the plug leading to the fuel pump- and have power- even with the key off. Does the key just ground the pump to run??
Also I included pictures - I have not found a fuse anywhere (is it near the ECU?)
Also- pertaining to the picture of the fuel tank/pump--how do I disconnect the fuel line?
I appreciate any help!

dissconnect the fuel pump wires via the plug. atart the atv to get the fuel pressure out of the line. place a towel under the connector to catch the dripping fuel. squezz the tabs of the white connector in the first pic togetther. then push the locking tab though the other side. then pull the fuel line off. to re install make shure the connector is clean. and reinstall in reverse.
i looked at a wireing diagram. there are 3 wires brown is ground, violet/white is the gas gauge ohm wire, and the red/dark green is the power wire to the pump. it seems the red/dark green is live all the time. but the fuel pump keeps the fuel system at a constant 39psi. it seems to me the pump will come on when the pressure becomes low.
you will need to prime the system when you put it back togetther. cycle the key on and off 6 times. wait 3sec on the on postion and 5 sec on the off postion. turn the key to start wait 5sec or untell it starts. if it dont start repeat cycling the key and retry.
