1991 Ranger Gas Gauge Problems

[McFuzzie]

I have a 1991 Ford Ranger with a 4.0L V6 and I'm having a little bit of trouble with my gas gauge. When I bought it from my Uncle a few years ago the gas gauge was stuck at Empty. So I figured the sending unit was bust, so I replaced the fuel pump/sending unit. The gauge seems to read correctly when the truck is off. But when I turn it on the needle goes up towards full. (So it's showing I have 3/4 of a tank, when I have closer to a half a tank.) Any ideas on what's wrong? Thanks.

misreading of a petrol gauge replace the sending unit propretly necesary ((loose and hole in the buoy))
