So when I first got my truck, I noticed that when I am sitting on a hill while running, the fuel gauge will move upwards, however when I am sitting on a downhill slope, the fuel gauge will move downwards, not the problem; in fact its quite normal. However, a 19-gallon fuel tank that is about four feet long and two feet wide, with the pump/float in the middle is a terrible design. My main reasoning is that when it says I have extremely low fuel (yellow/red fuel warning light), and I fill up, I can only get about 15 gallons into the tank. When there are only four gallons remaining, it sloshes around everywhere except the middle of the tank where the float is, I knew I should have gotten another model year up with the in-dash fuel remaining mileage gauge. Anyone else agree with this?

 

The tank design does not change nor will the issue go away with a newer truck. The truck has about a 50 mile reserve capacity to keep you from being stranded, I kinda like that.

You have to admit your knit picking pretty hard here, especially since Wisconsin doesn't have any mountains to drive on where it might actually make a difference.

If you want an accurate gauge ditch the hot dog tank for a fuel cell.

FWIW, I run an ultra-guage and it counts gallons left and current mileage. Also I have gotten just over 19 in my truck so you are not trying hard enough. I might be a bit hard on you but its honestly a small issue.

 

Its not the gas tank. Its a variable resistor design on the fuel pump for the gauge.

 

and ford gas guages have always sucked to begin with

 

I agree with blhde. I also have the same aftermarket equipment he does and have fit 19 as well.

 

its just a matter of how much you want to push your luck/drain your wallet lol

 

When I first got the truck it was 15 to fill it, so then it was luck. Now its 60 and I am trying to stretch it another day.

Although now that I have the CVPI, it gets a few miles better per gallon so I drive it more. Its a v8 powered couch and can be very fun to beat on.

 

I always reset my trip so I know how far I can go. That gauge will go way below empty. The most fuel I've ever pumped was 17.8 gallons. I had another 20 miles or so to go, I knew I could have made it, but it was -10*F out and I didn't see anyone on the road who would have helped me.
