Yep look at that trapped crud.
It will also trap water.
You can open the drain to let some of the trash out if you ever get tired of looking at it!
We had a 1982 300TD years ago that had a few tanks of veg run through it.
The veg acted as a cleaner and cut through a hard sludge that had formed on the bottom of the tank.
This released rust particles that would clog up the fuel filter after only a few miles.
After replacing the filter about a half dozen miles or so and getting stranded long enough to change the fuel filter and pump the primer pump about 100 times to fill the empty fuel filter, it was time for a solution.
Installed a sedimenter, then a 12V fuel pump wired to the ignition circuit.
Installed a new fuel filter and switched on the key.
Watched the sedimenter fill up with fuel with rust particles that settled to the sedimenter bottom.
After driving for 6 months, had someone bothering me to buy the 300TD.
After they made an offer I couldn't refuse, decided to check the sedimenter.
It was 90% full of rust particles that looked like fudge.
Removed the unit, disassembled it, emptied all the rust, cleaned and reassembled/reinstalled it.
Decided to check the filter and it looked brand new.
Turned on the key and 12V pump filled the fuel system, and the new owner drove away.
Saw them about a year later and they said the vehicle ran perfect every time.
Have used a sedimenter & 12V fuel pump ever since.
Never have to dick around trying to prime the fuel system... just switch on the key and any air is pushed out.
