Wow Bill! I stand humbled

That looks amazing! Isn't that the 261 waterpump with 2 holes for fittings? I was assuming you had a 235. Is that a 261? I just lost out on and edmonds intake on Ebay last week. I'll have to live vicariously thru you for now. btw, I think your set up as is will work as good as it gets for water heat. Nice job!
