Question for anyone that has had a problem with this, just purchased a 2012 international prostar i have only went about 600 miles and fuel gauge has worked ok then all of a sudden the truck dies come to notice im out of fuel yet my gauge still reads 3/4 what could that be?

It's a stuck fuel gauge. I could not resist. These newer trucks run on sensors. At one end there is a feel sensor in the tank on the fuel pump that has a slider that moves with the fuel. It could be stuck. Or you might have a bad fuel gauge on the dash. The dash gauge is the cheapest to check. Buy a new gauge (about 15 to 20 dollars) and see if that fixes it. If it does not then it might be in the fuel tank which will cost a lot more. In either case if there is warranty doing the work yourself will void it.

I drive that exact truck myself, same year and model. My fuel gauge will start spinning around in 360 degree circles at random times while driving. It is like the Exorcist truck or something.

I drive a 2015 ProStar, I have noticed that my fuel gage reads about a 1/4 tank lower than my actual fuel level.

And this is not just limited to the Internationals. I have driven Cascadia's, Peterbilt's, Kenworth's, and they all read a little lower than actual fuel level.

Yours on the other hand is extreme, but like GuyJax stated, it might possibly be a warranty issue with yours.

So before you start any repairs on your own, check with the International dealership to see if possibly there is a warranty recall that you are not aware of on your truck.

It's not the exorcist truck, it's just an Intertrashional. My first truck was a 2011 Prostar, and among its various and sundry problems (and believe me, there were MANY), the fuel gauge would sort of wander around. One minute it'd read full, 5 minutes later it'd show 1/2, another 10 miles down the road it's reading 3/4.

I had this problem in my Kenworth T700 and it was a fuel sensor within the tank. Easy fix!

There are 2012, 13, and 14 where I work and I have talked to at least a dozen drivers that have this issue.

And reading the posts here, I guess it is not just limited to International ProStars.

My first trainer ran out of fuel twice during my training due to the fuel gauge not reading properly. That and him running only on fuel enough for each load. But that is a story in itself. LOL

On my truck, it can vary at times up to 1/4 of a tank or a little more at any one given time. And that turns into several hundred miles.

My first trainer's truck was under warranty. They replaced the sensors and gauge twice to no avail. He still had the issue when he got rid of the truck. So I guess it is something in the reading system.

I just make sure when I give my fuel readings for fueling stops, I give the next lowest on the gauge. It is an expensive road call for fuel.

Keep it safe out here, the life you save might be your own. Joe S.
