I just have the one filter that's and inline clear. It's not even a year old and looks good. Filter is right before the pump. I checked the carb (man. choke) and everything seemed to be moving properly. I had a problem last year with major surging at highway speed. It ended up being the ign. module (well, we changed the pump out with a new one and it still did it, checked all fuel lines, nada. Checked plugs..even replaced them while we were at it, fine. Finally changed module and it stopped surging).
But it has run fine since then (and before then) up until last week after a really cold night when it started doing this. I'll check for the condensation and also add some additive.
I'll post back tomorrow if anything comes up. Thanks for any more info.
