No I'm sorry I don't! :shrug:
Basically, since you need to drop the gas tank, you'll need to make sure you only have 1/4 tank or less so the gas tank isn't so heavy lol.
Put a floor jack under the gas tank, unbolt the gas tank mounts and slowwwwwlyyyyyy lower the tank about 6 inches. You're gonna have to reach your hand up and snap off the wire harness/electrical. ****Make sure you don't pull out the wires from the harness!!!!!!***** Everything on top of the gas tank must be disconnected before you drop it. Lower it down and pull out the sending unit and pop the new one in, very simple. Then re-mount everything. Hard for me to describe without pics of the top of the tank. I'll see if I can find some pics online.
Try this: (You'll be blindly reaching up to disconnect this stuff so check out the pics)
