Question Running out of fuel at 1/4 tank

Sometime last summer my fuel gauge in my truck stopped working. When it worked, I would usually run my truck down to an eighth of a tank before I would fill up. I had even seen the gas light a few times. I would generally get about 550 to 600 miles to a tank as long as I was doing mostly highway driving. Since then, I have been filling up by the miles on the trip meter. In the last couple of months, I have only been getting about 450 miles to the tank and just took it to be bad city mileage. Over the holidays, I finally got around to pulling the bed and replacing the float in the fuel tank. The old one was gone. I got a new one from Mopar so it was a stock part. The fuel gauge started working again and everything was fine. Well, I was coming back from a backpacking trip earlier today, and got back into town. I pulled into a left turn lane and was waiting on the traffic when my truck just shut off. I looked at the fuel gauge and it was still showing well over a quarter of a tank. I managed to get it started back up and ran on fumes to a nearby station and filled up, then had to crack the fuel lines to get her started back up again. The truck only held 28 gallons filled all the way to top. Why is my truck running out of fuel when there is should still be 6 gallons left in the tank and it is showing that fuel on the gauge? For some reason it is not picking up all the fuel. I know it holds more that 28 gallons because I have put over 30 gallons in before and thats not cramming it. I have talked to a couple of other people who have had this problem with their dodges and I would really like to know how to fix it. I don't really like not being able to use all my fuel, and would like to have it back to normal. Sorry for the long post, but any help would be appreciated!

You might have the float rubbing the side walls and hanging it up. I had the same problem with mine. Just loosen the cap and twist the sender the oposite direction. You might have to swing it till it taps a wal to figure out where your at... This can be done without pull the bed or dropping the tank...

Yeah, I thought about the float hanging up, but I made sure it was in the middle when I put it back in and it still doesn't explain why the truck isn't using all the fuel in the tank. Thanks for the thought! Any other ideas?

I thought about that, but I changed the guts of it, but it still doesn't explain why I am only burning 28 gallons of fuel. Its like its not picking all of it up or something. Thanks for the thought though!

The Pump And Pickup Are Able To Slide Up And Down. Maybe It Has Bound In The Up Position When It Was Re-installed.you Can Drop Your Tank Without Pulling Your Bed. Just Unhook The Wires And Hoses Before You Drop It Down All The Way.

I'm not really sure what you are referring to, but I don't have an in-tank pump and I didn't move the actual measuring unit that the float attaches to. I was very careful to make sure that the sending unit when back in in the right position so the float wouldn't hang up. There are even arrows on it and the tank to make sure it is lined up properly. I could have dropped the tank, but I decided it was much easier to just pull the six bolts out of the bed and lift it up instead of trying to drive 600 miles to empty out the tank or trying to pump it out. It really wasn't that hard, it just takes several people. I may have to pull it again and look at the pickup hoses in the sending unit, but I hate to do it all and that not be the problem. I really don't have any idea what the problem could be.
