Is there a way to calibrate the fuel guage? I put a 2" tank lift on and my fuel guage is way off. I have the 4" digital speedo/analog tach from HD. Thanks

 

Yeah, it's called an odometer.

 

Fuel gauge on a Harley is as useful as **** on a bull. I agree with OldEnuf2NoBtr, use the A trip odometer for fill ups and the B for oil changes.

 

I got a lift on the front of my tank, and the same speedo. There isn't much that will make them more accurate.
At least it will say you are lower on fuel than you actually are. So you won't run out. Like the others have said they are not all that accurate anyway.
When it says you are low, get fuel. Or if you don't want to stop as much figure out how far you can go on a tank, then use your trip meter to keep track.

 

Well, I guess I'll I use the trip a fuel measurements. Thanks guys.
