Been there a few times with those bronze filters, or whatever they were made from.I changed many Q-Jet in-carb mini filters. They made slim wrenches to hold the lock nut.
If your vehicle cut out under load, this was the 1st thing to check.
Worst I had, being an Allis Chalmers tech back around 1980 or so. Farm sale that afternoon, sub-zero temperature. Called out to get a 185 diesel tractor running. Fuel tank was located in front of the operator's station. Cap on top and a straight look down into the tank. Fuel looked pretty thick.
I stuck a pry bar down into the fuel and pulled it out. I could see the hole from the bar after it was out. Kind of like you stuck it into a jar of jelly. Worst case of jelled diesel fuel I ever encountered. Filters were all plugged too, being the most restrictive part of the system.
Had to get a tank truck out and water the diesel down with kerosene. Space heater blowing on tank, fuel lines, injector pump, etc.
Then getting your hands wet with fuel at -10F. Many trips to pickup truck to get warmed up. But we got it running.
