2004 Parker 2520 XL fuel gauge reads full all the time....

the yamaha fuel gauge is reading full all the time. checked the wires and they look good, took the sending unit out of the tank and moved the float up & down with no change to the reading on the gauge, it still registered full.....
please help.....

do asearch for Yamaha fuel gauge, there are about 20 returns....sounds to me like you have a bad connection which is increasing the impedance to the gauge. you might also check classicparker site, I recall seeing the same issue there.

Mine does that also. It's a bad fuel sending unit (the thingy that tells you how far down the fuel is in your tank). It's pretty common.

I haven't bothered to replace it. I use the flow meter instead.

yes, I already checked the wiring, it is all in tip top shape, I removed the sending unit from the tank, and that looks like it was brand new, but working the float up & down did nothing to the gauge reading....gauge still read full like when you first turn the ignition on.....
