understand fuel gauge!? how much left?

[Radshooter]

but the first half of my tank always last longer than the second half. Therefore, the gauge or the sending unit in the tank is not very accurate.

Mine too. Whenever I fill up to the top by drizzling in the last 5 gallons, I can drive 120 miles or so before the gauge even comes off the full mark.

My fuel gauges only know full and empty. I always take a new vehicle and run it low as possible then see how much it takes to fill it. I run lower each time until I have come close to running it out of fuel. Once you run it low and know where the gauge reads and how much fuel it takes at that point, you have verified the accuracy of the gauge. My wife is the master at running low on fuel. She never runs out, but it always comes within a half gallon or so of the tank capacity. I have run out several times, but always had fuel with me when I push it. I figure it has a 34 gallon tank, so might as well use it all.

Fuel gauages are just a ball park indicaor (sp?) it's not accurate your lucky if it reads empty before you are empty. You can't expect it to read the same at the same level each time over time. Then from truck to truck each gauage reads diff. I changed the sender when did the heavy duty filteration the readings on the gauage were very diffrent from one sender to the other. The old sender, the gauage would not start to move off the full mark for the first 130 miles. Now with the new sender it starts moving at 55 miles. I use to get almost 400 miles and the gauage would still be reading over 1/2 half full. With the new sender it's now reading less than half a tank at 298 miles..... So, my point is this when you fuel up re set your trip odomeeter to zero drive when you re fuel check your Miles Per Gallon and re set the trip odomeeter. that will give you a real gauage on your fuel use and how much is in the tank. then your dash gauage can break and you'l never run out.

Like Jim (Jelag), I have taken mine to 30 miles past 0 DTE. Never again. It was one of those "in the middle of nowhere" and I rolled the dice. Pulling my TT on top of it. Don't know how I made it but I will tell it took 33 gallons at the pump. Like I said, never ever again.

I have been there once also. I was about 50 miles past 0 on DTE, my fuel gauge was so low it looked like it does when off, and my SG was reporting 0 from the fuel sender. I went about 10 miles past 0 on all 3, but still had fuel pressure. I didn't top off as fuel was about . 50 more than another 20 miles, but I was EMPTY. I had gotten caught off guard having to leave the campground to help a friend and all the small town pumps were closed for a holiday. I too was towing at about 11 mpg.
