Reel time--You described exactly what is happening.
The black canister was further back in the line when I noticed it was leaking gas a lot under stress. I crawled under and could feel that it was not seated correctly. Took it to a shop in Wyoming and they unscrewed it--no filter inside, threading damaged and O ring flat as a pancake. The were unable to get a replacement canister and placed a filter directly on the line. The setup I now have is 2 filters directly on the line. I'm going to take a look underneath and see what everything looks like near the engine plus look at the radiator for blockage. If the lines are real close to the engine, I'll probably heat shield them.
