I replaced the original defective sending unit with the new one maybe 2 years ago. There is a sock on it that is larger than the stock filter (more surface area). I should mention that I've only put less than 300 miles on this truck since I bought it in March of 2024. Checking for excess crud on the sock or at the fuel pump inlet will be the first thing to check when I drain the tank. A couple of days ago, when all of this stalled truck by the side of the road stuff was occurring, I stopped by a buddy's house when the truck first started running poorly and we pulled the carburetor off the truck. I cranked the engine and observed what appeared to be a good amount of gas coming from the fuel line into a coffee can. The glass bowl fuel filter just in line before the carb has never shown any sediment. We opened up the carb to look for any obvious contaminants that might be blocking an orifice and saw nothing. We blew out all of the passages with compressed air and reassembled everything. During that disassembly/inspection/reassembly time, the engine cooled off considerably. Then came the long highway-speed uphill climb with all of the unplanned breaks by the side of the road. So if the fuel line sock is clogged, it took 300 miles traveled over 2 years to do it.
That's way more information than you asked for, Carl!
