5 gals still in the tank and it acts like its out of fuel

[The lawn shark (tls)]

Ok so the last 4 times I've filled up it was because the truck would start acting like it was out of fuel and I would go fill up and only be able to put 18 to 20 gals in it....I know for a fact that It will hold 24/25 gals because I've put that much in it before....the gauge reads about 1/4 tank everytime it starts running out of fuel....Today it ran out....truck shut off...would'nt start put 2 gals in it out of a can then drove one mile to the fuel station and took 18 gals to fill it so it took 20 gals....I know there has to be like 4 or 5 gals still in the tank?????????

Opinions?????????
Help????????????

Maybe a corroded line in the sending unit.
Also could be a clogged sending unit. Thats all that is down there. A float, sending unit. and screens. If one of the lines corroded then it could possibly act like it is running out of fuel.

Run it down to a 1/4 tank at your house and when it shuts down, pull the bed up and open the top of the tank and see how much fuel is in there. I know mine will hold 28-29 gallons to the top of the filler neck.

I've put 32 or 33 gallons in mine a few times.

There's a fuel pickup "sock" in your tank that is famous for breakin off. If you call any dealer in the country, they'll tell you those symptoms indicate a broken sock. They might ask you if you've had anything hit the tank and if you tell 'em no, they might look for other problems for a few hours, but eventually they'll pull your tank. I dunno why it breaks off. They get old and brittle I guess. The airdog kit replaces all of that, if you're look at gettin one, now might be the time.

I think I had a problem close to that as well. My gauge read about 1/4 tank and I ran out of fuel 5 minutes later and I had to go get 5 gallons of diesel with motorcycle to put in then it barley started and smoked white for a while. I didn't get fuel light of anything.

No problem, and IMHO havin done it both ways both times, it's easier to drop the tank on these than it is to remove the bed. Probably safer too.

The pick up on my rear tank broke off and It had several gallon left it the tank.
The plastic pick up just rotted off the metal tube. That is the only time I ever ran out of fuel in the truck, It sure caught me off guard.
