Hmm, you might be onto something.
A few months ago, I complained that my fuel gauge was very erratic.
Since then I've lost about 100 miles off the range, I'm never able to get more than 430 miles out of a tank. I don't have a bi-directional scan tool, just a regular one, so I connected it and looked at some live data while driving. I didn't see any misfires, but maybe this is fuel related rather than transmission???

All of a sudden the fuel level is way inaccurate.
It has a 31 gallon tank, with a range of about 530 miles. The gauge is digital. I can fill up the truck completely, and while driving, it will "lose" 2-3 miles of range over a short amount of time. The worst I've seen is that it shows about 1/4 tank left after being filled up completely and only about 80 miles of driving.
No, this isn't a leak either, because while driving, and randomly, it will slowly creep back up to the correct "level", both the level and the range.
Today, I ran the tank down till it said "LOW", put in 25 gallons, and when I started up the truck, it showed that it was only 3/4 full and that the range was 376 miles, which is obviously incorrect. Then, while driving, it slowly crept its way up to 7/8 full and 476 miles, which was better, but still incorrect.
Does it sound like my fuel pump is bad and needs replacing? I've also once heard a super loud banging back there, underneath the seat, in the tank area.
