New here and to owning a sport trac I have had it about 2 weeks and noticed the gauge was staying to full then drop some while driving so I filed it up and set the trip to 0 and now with 110 miles its just below 3/4 tank. when I got in it tonight after work it was at just below 3/4 and when I looked after a few miles it was back to almost full then slowly dropped back to just below 3/4. I'm not to good on electrical just mechanical. Has 169164 miles on it. Thanks in advance for the info.
