7.3 fuel problem

Hi there guys im having a problem with fuel in my 7.3. Its a 2000 and if im not mistaken originally comes with a 29 gallon tank. Well i always like to fill it up when i reach the quarter tank mark. A couple days ago i went below that mark and the truck had no power when you accelerated it and started sounding like it had a lope tune. I put-putted to the gas station and filled her up and boom shes perfect. But the gauge still said i had a quarter tank. So now to avoid this scare i just fill it up at quarter tank and dont dare go under that. Evey single time i fill up it stops right at 19-20 gallons. So if i have the 29 gallon tank shouldnt i still have 9 gallons in there? Why isnt it pumping the rest? Or maybe i have a smaller tank than stock and its just a 20 gallon tank and my gauge is off? Please help! Thanks

the drop tubes for the fuel pumps are known to break off in the tank right at the 1/4 tank level on the gauge. plenty of threads on it and how to fix it. good luck.

I just did this and the harpoon (more gas in tank) mod. They're both pretty easy and I took a ton of pics. See the build thread in my sig for pics. Good luck!

Just for context... after having done the H&H mods on my tank, if I run it down to empty, I've been able to put as much as 34 gallons of fuel in my "29 gallon tank" by dribbling it in until I could see liquid fuel at the top of the filler neck.
