Thanks for the detailed description, Casey - that sounds easy enough. My intake hose already has a "Y" fitting like you describe, so all I need is a bucket and hose. I could use quick fittings (like air hoses), which would make the connections super easy.
Still thinking about the FWC conversion though. Maybe I'll pull the head and exhaust manifold this winter and see what the insides look like. If its anything like the outside (like new), I might pull the trigger on the conversion. But if things look pretty far gone, my money is probably better spent elsewhere (like savings towards a repower). I'd sure like to keep this baby running - it's basically perfect for the application (and already paid for).
