This is for bikes with a strip-type sending unit, not floats. My bike is a 2005 K1200S. The whole thing took about 1-1/2 hours. Apparently, the fuel sensing strip is prone to cracking, leading to an open circuit. This fix sends a high voltage charge through the strip which fuses the break back together. I bought a BBQ grill ignitor at Home Depot for $13.
It comes with a wire to the ignitor and a ground wire.
I cut off the ignitor and spliced on a female spade connector. I heat-shrinked them to prevent any arcing.
1. Fill'r up! Gasoline must be vaporized and it needs air to burn. And we de-efinitely don't want that. Fill the fuel tank to ensure the fuel strip is submerged to minimize the chance of anything ..uh.. bad happening. 2. Remove the seat, side fairings, and fuel tank side covers. You'll see in the photos that I took off the center part of the the fuel tank cover, but that is not necessary. Either way, I kept the fuel cap tightly fastened. I'm not a big fan of explosive vapors in my garage. I also disconnected the battery.
3. Remove the two large bolts that hold on the fuel tank.
4. Lift the tank up and out so you can gain room to get to the fuel pump.
5. Here's your target. Unclip the connector on the right side and pull the connector out.
6. Now you have access to the pins you are looking for - the center two pins, pins 2 & 3. You can see the pins in my mechanic's mirror.
7. Connect the BBQ grill ignitor to pins 2 & 3. The female spade connectors were small enough hold onto the pins. Here they are (they white wires) connected and ready to go.
8. Take a deep breath and know that many have done this before (I rolled mine out into the driveway anyway, lol). Click the ignitor 5 or 6 times. 9. Snap the fuel gauge connector back in and connect the battery. Turn the ignition switch to on and wait 90 seconds for the bike to go through its checks. 10. Take a step back and realize you are awesome! Laugh that you are surprised.
11. Put the bike back together and you are good to go.

Voiam sa va intreb daca a mai facut cineva asa ceva, si daca nu vi se pare putin cam periculos, chiar si cu rezervorul plin.
