This is a pretty interesting thread, eh? I took my tank to the Renu-USA guy today, that'll set me back about $125.00. I ordered the older style of sending unit from Chevy Duty and that type doesn't have the "up and over" fuel line with sock attached. My fuel line goes thru a small petcock on the bottom of the tank.
Yeah, common practice seems to be having a filter between the fuel pump and the carb, and that's what I'll do. Also took a quick look at the plugs, #2 and #5 were pretty sooty, although the engine seems to run good. Picked up a rebuild kit for the Rochester and that'll get done after the tank is re-installed.
