Fuel gauge problem.

[john 087]

my low fuel light comes on and off dimely when gettting low, but when its just under 1/4 full comes on bright and stays on. have my fazer over 3 years now went for a spin the other day the gauge started again.

Yeah I find that too. The gauge is dodgy but I've found I can usually trust the light.

Mine started playing up yesterday, i've done 60 miles since top up and when sitting ticking over it's sitting at 3 quarters full which i expect but when I move off its moving up to full and back to 3 quarters again. Also when I turn ignition off the gaugue drops very slowly maybe 20 seconds, any ideas?

I'd guess that the up-and-down bit is just a result of how the float reacts/moves depending on the actual fuel level in the tank. So the changes under acceleration are just due to the fuel moving in the tank. Probably does similar under braking? It does seem a little odd that it'll do this, yet when you switch off it drops slowly. Just a design thing I think.

....hi cambo mine does exactly like yours as nick says mabe design thing?..mines a 02 foxeye with only 6k on clock and as been same since buying it with 4k!!....

Definitely a design thing guys, I think up until recently all vehicles had gauges like that. I know every car I've ever owned (apart from my current Mondeo) took at least 30 seconds for the fuel gauge to read correctly, so don't worry about that.

When the revs drop or on tickover the needle drops to where i would expect it to be due to distance travelled but as soon as i open the throttle it just goes to the top.

Mine was jumping all over the place. Returned to the dealer for them to sort out and turns out the sensor had gone (even though I got readings from it).


We'll wait and see!!

Even when there is little fuel in the tank, it goes to a full reading under acceleration? Sounds like an electrical problem on the sensor/wiring.

Had a bit of trouble with fuel gauge last week! ended up being "blue tissue" paper! i've put it down to the fuel pumps having been serviced & the mechanic! forgetting to clear up behind them??
