I have a 95 dually with an issue. My front tank is full and the gauge reads E. I thought that someone maybe stole the gas but I went to fill it again and it wouldn't let me. It was full!!! Here's the issue. I figured that my gauge broke so I drove with it on the front tank. About 10 miles in I shifted into 4th and lost a lot of power. It wouldn't go over 2k rpms. Also the check engine light kicked on. I didn't think it could be the fuel so I limped it to my local shop.(couldn't go over 30). When I got there I realized that it would appear that I was on E so I put it to rear tank. There diesel tech came looked all over said it didn't have any codes and he shut it down. I went to try to move it to the back lot and when I did it ran like a beast again. This was 200+ miles ago. The only other time it had any issue was 2 days ago when I decided to try the front tank again. Same thing happened. Soon after I switched it back to rear it ran right. There is 100% no doubt fuel in the tank. That is certainly not the issue.

Any help would be awesome.

So just to recap:
* Truck runs normally on the rear tank
* Front tank - gauge reads E, truck runs bad / doesn't run, unable to put more fuel in
right?

Sound like the tank switcher is not fully switching to the front tank.

Not sure if this is relevant but I have noticed that over the past few months that the gauge would only show 3/4 full when full.

No, it's more likely the valve down on the frame that's at fault. The valve fully operating is actually what switches the signal between the senders and the gauge. So it sounds like when you switch from rear to front, it doesn't fully open the valves for the front tank, and thus doesn't throw the switch for the gauge to the front sender.
