Fuel Gauge Innaccurate

[darkspork]

I have a question about the fuel gauge in my 2003 Ranger. The fuel gauge seems to be off by a few gallons. In the past two fill ups I've been averaging just under 15mpg (not bad for 60% city driving with 4Hi on 25% of the time), this isn't an issue to me but my fuel gauge seems to be inaccurate. When I got the truck the gauge read at about 1/8 tank, I filled it up and it took 13.8 gallons. Next fill up the fuel gauge was reading a little under 1/2 a tank and it took 6.8 gallons to fill up. The last fill up it was reading at a little over 1/3 tank and took 9 gallons. So the gauge seems to be off by a few gallons. I'm sure this is not entirely uncommon but I was wondering if there is anything I can do to make my fuel gauge more accurate. Thanks.

According to "howstuffworks.com" there is always going to be some error in the fuel reading, it all has to do with that float in the tank, you would think by now someone would have come up with a better system for the newer rangers.

My last two cars were a whole lot more accurate (1992 S-10, 2003 Pontiac Vibe). However, the 1974 Chevy Nova I had was about as inaccurate so I usually went off of miles since the last fill up. I guess I'll do the same on my Ranger. I know some margin of error is almost always to be expected, I just figured it would be smaller on the Ranger.
