To replace the fuel pump on your truck you will need to drop the fuel tank down .The pump is located in the top side of the tank.It may require a special tool to remove the hold down ring around the pump.
Fuel Pump Lock Ring Removal Note
I have found the fuel filter and removed the shields and the rear clamp. I have the proper tool to remove the front clamps but I can not find a way to unhook the clamps. I have spent over an hour under the car trying various ways to get the tool to unhook the clamps but I do not have any information on how the tool works, how you grip the clamps, or any other information that would help me to unhook the 2 front clamps. Your information on where the filter was helped greatly, but I still can not get the old filter off or the new one on. I am probably going to take it to the dealer today and let them finish the work unless there is additional information you can give me.
