Thanks for the quick response. I used a heat gun and plugged in the heater and it was running within 20 mins. I just added some Howe's treatment and topped off the tank and ran it around for 20 mins. Running good now.

I filled it up 2 days ago, Citgo in Burlington, MA, they use a fair amount of diesel so I agree, I would think it is already the winter blend. I'm also afraid you might be right with the fuel catalyst being where the blockage was. i concentrated the gun on and around that and around the fuel filter housing and lines nearby. That fuel catalyst is not that restrictive, if at all, but I think it may give a good home for moisture/wax to start to develop and hang out. I'm hoping with treatment I can keep things running well.

Any thoughts on the Fass fuel system or similar lift pump systems? I'll check Kennedy Diesels site also for ideas, but I think I'm adding one of those soon as well.

Thanks again for the responses and help.
