I posted some of this on "show us what you see" but now I have a specific problem,
1994 F350 7.3L IDI ( International Harvester) with 155K miles.
10 years ago the "shower heads on the fuel lines in the tanks fell off. I've been running only on the top half of the tanks. On Monday we replaced them so now the fuel pickup is on the bottom of the tank.
If you notice the pickup tubes are discolored. I ran my finger on the tube and it had a fine sandy/grit that easily came off. The rest of the tank appeared ok so we put it all back together.
This is all that we could find of the old shower head in the mid tank, the rear tank we couldn't find anything. We looked closely with a flashlight and the tank didn't appear to have any issues. The black pieces would easily crush in your fingers.
After the shower head replacement I drove the truck about 100 miles and got the rear tank down to just under 1/4. The truck ran fine with no issues.
Yesterday I changed the oil and fuel filter. It has been 4 years since (3k miles) I replaced the fuel filter. I drained it 2 years ago (about 1k miles) per my notes and I think I drained it last year but didn't document it. Whenever I change or drain I always do it into a glass jar and the fuel has always been very good with no water, or sediment after it sits for a day.
This is the top of the filter, it's a layer of "sandy" type debris
This is the water drain at the bottom of the filter. The drain clogged and I couldn't drain anything out of it. It's all a very fine sandy material.
The next two pictures are of the fuel that was in the filter, there was no green it was a hideous red liquid.
I drove the truck yesterday about 5 miles on the 1/2 full mid tank to put 7 gallons in the rear to help slosh stuff around. I tried to drain the fuel filter when I got home and nothing would come out (so I'm assuming I've already sucked up another load).
So my question is to anybody with some old equipment that might have seen something like this before.
What do I do?
1. new tanks are about $200. total, not bad for the money, just pulling the bed again and installing,
2. keep running it and draining / changing the fuel filter ? not what I prefer, how long before it clears up? I don't want to be draining/changing fuel filter (they cost $20.) for the next 9 months or 1k miles
3. what I don't want is if any of this goes to the IP or injectors to loose that component, I'm not sure how much of an issue/possibility that is.

) the sand/rust material at the bottom of the filter is definitely the cause of the color. The jar with the fuel has lightened in color as the debris settles on the bottom,
