So I've noticed since I bought my truck back in September, that even after I 'fill up' the gauge would never go much over 3/4. I can run the truck down to where the lie o meter says I only have 20 miles left, 'fill it up' with 20-22 gallons, then drive home, let it sit a while, and then dump some in out of a can but it's hard to get a gallon to fit. So I'm assuming 'E' isn't really empty? Definitely don't want to test that theory by running it past 'E' though. So here's my question, I'm about to install an airdog, is there anything I can check-fix-replace while I'crazo got the bed off to try to fix it?? Thanks?
