Fuel gauge 07 Southwind

[Neumann]

I filled up my tank (gas) when the gauge said 1/2. I put in 48 gallons in a 75 gallon tank. This means I have only 27 gallons left from 1/2 to empty.
I have somewhat noticed this before but this time I was careful to make sure it was at a half tank before filling. No wonder the last 1/2 tank goes so quick.
I guess I should check it at 1/4 & 3/4 if I'm close to a gas station at the time.
Anyone else have this happen.

It's not unusual. Most fuel gauges actually have two ranges, Half-->Full and Empty-->Half, so there is a sort of gap in the center where neither is very accurate. Sometimes you see a drop from 5/8 to 3/8 tank over a short distance.

Ford will tell you that empty on the gas guage will be 5 gal. left(your reserve)

I have put 72.772 gal in the 75 gal tank which meant 2.228 gal left. I guess I was really into the reserve. I don't let it get that low anymore. I don't remember what the gauge said but it must have been on empty. Glad the DW does not know this.
