So I have three 7.3's, two OBS work trucks and my wife's super duty. That makes five diesel tanks that have years and years of gunk, water and who knows what inside of them. Dropping all five tanks and thoroughly cleaning them is the best practice. That's not going to happen, is there a "snake oil" treatment I can dump in the tank that works? Asking for a friend.
I don't know about a snake oil that'll clean them, and if they're very dirty and something can clean them the filters will possibly plug up. Biofuel is supposedly a good cleaner.
I dropped the tank in my Ex to replace the foot and the tank had just a thin black film on the bottom, nothing I woulda worried about. And some or all of that may have come from my WMO, even tho I filter it well, I still find some stuff that settles out and lines the bottom of my catch tank. My Ex has over 400k miles and it didn't look like anyone had been in there recently. I don't think I'd sweat it unless you're seeing signs of a problem. If you're wanting to clean them to be super diligent a snake oil isn't the way to go, you'll never know if there was any buildup nor whether your snake oil got it out.
On both my superduty truck I dropped the tanks and other than a few little cruddies which the filters took care of there was no weird stuff in there. The old metal tanks may have some more crap in themas rust might be a issue but diesel is very oily. When i dropped the tank on my old GMC and it was a steel tank. There were no rust patches or unusual things.
Unless you’re having a issue like clogged fuel filters and need to drop the tank I wouldn’t waste the time.
I just cleaned 4 15 gallon and 1 55 gallon tanks with water and going to let them bake in the sun tomorrow. Bringing my own fuel on a upcoming trip since I can get it here a lot cheaper. Maybe some degreaser if it’s bad and a ton of water. I’d be more concerned about the screens.
Is there a fuel filter in the diesel tank on a 2000 F250 7.3.
How many fuel filters are there on the engine all together?
The truck gets to a 1/4 tank of gas and starts losing power.
Have changed the fuel pump and filter on top of the engine twice.
Just as soon as i fill it back up with fuel it runs fine till i get to
a 14 tank it starts again.
Any suggestions?

My guess for you is that the pick-up foot in the tank has broken off. So, while you're in there fixing that there are other in-tank mods you should look at doing. Hutch mod is one.
Hearing y'all found very little gunk when dropping your tanks is encouraging and kinda puts my mind at ease. I love how tough and resilient this engine is. But I still try to maintain them as best I can within my budget and time constraints. I also appreciate this forum and everyone's help , thanks
Below are some pictures I took focusing on the interior of the tank. As you will see, there is still a few gallons of fuel in the tank when I removed it from the truck. I had supplies and prepared to scrub and clean the inside of the tank. That was not necessary at all as the tank was very clean, even on the bottom. There was no sediment or debris (other than the pickup foot) and I quickly decided I did not have to clean the tank interior. I have since cleaned the screen filter on the Racor a couple of times. I inspect the Racor filter each time I get under the truck to change the oil though. A quick glance with a flashlight indicates if I need to empty the filter or not.
