Flush mount fuel gauge problem
Any of you guys running the Harley flush mount fuel gauges? I've had mine on for about 6 months now and love the look of them.
My only problem is mine seem very inaccurate and unreliable when it comes to my actual fuel level. Sometimes I will have 3 dots left on the gauge but my low fuel light on the speedo will be on. Other times I will have 1 dot on the gauge but no light on the speedo. I usually go off my mileage on the trip anyway, but it would be nice to have a consistent gauge also. Anyone else have any similar problems?

+1 here.
Mine is only for show, I can never use it as a fuel gauge.
If you find a fix or a way to calibrate post it.

Mine works as advertised. As I consume more fuel, less lights illuminate.
Kidding aside, mine is somewhat accurate and it coincides with the gauge on the speedometer.
I look for gas when there are 2 bars lit. When I see only 1 bar, which I don't let happen often, I look at my distance to empty estimate. At 25 miles I'm on fumes so it gives me an idea of urgency to find gas.
If I want the most accurate estimate I look at the trip odometer I use for miles on the tank.

Can you recalibrate it? I have the PM LED fuel gauge on my '05 and it always reads full and when I calibrate it it works in reverse. I suspect I need to change the wiring in it but I have not messed with it yet. I always go off mileage but that can vary widely as the 117" gulps fuel when hot rodding around town and gets amazing mileage when cruising on trips...

I mostly bought mine for looks also, I was just wondering if anyone else had the same issue. It's not a huge deal for me, I usually go off the trip odometer anyway. I will have to do some searching and see if there is a way to calibrate it. If not, it still looks 10x better than the stock gauge and fuel cap!
