Your post should have been posted in a different section to get faster results...No Problem..
The Fuel level Sending units are Located on the Bottom of the fuel tank ...You Must remove the plastic covers ...will see a allen plug on the sender to drain the tank...It works best with the Factory tool for draining the fuel out..The Tank has two sides..Then Remove the ring for the sending units...A Factory tool is need for that also...Then remove the sending units.Note Mark the Location of the Old Fuel Sender BEFORE you remove it...
But It can be done without the factory tools...Good Luck
