Fuel Gauge Question
From my understanding the fuel gauge floats a 1996 f250 ps. It shows I have less then a quartet of a tank left so I stopped to get fuel. When I tried to put fuel in there the pump kept stopping like it was fuel. Once I looked in there I saw the fuel up to the top and then started going down. Then I tied my rear tank and it did the same thing. Any idea what could be causing that?

the breather lines on our trucks are just really really poor.
Look up the "harpoon" mod.
It will give you instructions on how to gut the pipe and run new lines.
DZL jim has it on his site, guzzles, and a bunch of guys on here have it. Harpoon is the correct name for the mod, but some people call it other things.
just a re-route for the air and a filler gut.
It's a poor design cause the inner tube doesn't go far enough into the tank, so the air cannot escape while your filling up causing fuel to back up.

I guess first off, Is this the first time you have filled the tank? Drive it some more and see if the level on the gauge keeps going down. That would rule out bad gauge. If it does keep going down and the gauge is reading fine. Then as Talyn said, filling these trucks up is a chore and it needs to be done slowly. The handle will keep stopping if you just set it to its highest point and let it fill. You need to control the flow of the fuel from the handle at just under the lowest notch. It will flow there and will kick off when its full.

I can only fill my rear tank on a good day. The front doesn't give me as much issue.
Dropping the rear one will make it easy to learn to do the mod, cause its easier to drop than the front, so if its cold there, you can get that one done easy and have one tank that works till it warms up outside.
I doubt your having any float problems at all, its just the air coming back up.

I agree, if you rule out a bad gauge then look into doing the filler mod.
Performance Injectors for 7.3L Ford Power Strokes
That's Jim's write-up and I used that for doing mine. The part numbers he lists for the new roll-over valves are now non-existent, but on mine I just used brass elbows instead of the valves. Works great and now it only takes about 5 minutes to fill up both tanks, and I have a 38 gallon rear tank on mine...
