The pump has a filter sock on it.
The bottom screen is a very poorly designed pre-screen for the pump. It is not required.
Not only that, but we use a plastic fuel cell that is 100% sealed and pressurized.
What would make it a "dirty ass tank"???
The only chance any airborne dust or dirt has to enter is the 2-3 minutes you have the fuel nozzle stuck in the filler neck. I just don't see a great amount of foreign objects entering the fuel cell.
You are more likely to get FO in the tank and subsequent problems by going to old or cheap gas stations.
