I have not done it yet, but I need to. I heard it's a bear because the pump is inside the tank. So, you need to either drop the tank, or remove the bed to get to it from the top. Someone told me removing the bed is easier because there are only 4 bolts. However, he didn't say anything about removing all the wiring, bumper, fuel tank feed line, etc. I'm really not sure which way to go. I hope someone will chime in and tell me.
