Now you've got me interested. I was concerned about the failure mode, but having 2 of them. Hmmmm. What does the stock (3rd gen) pump weigh? What has to be fabricated to hook them up? What do they cost? A nice extra would be a remote controlled valve so I can squirt PL when he looks into the cowl. :) > Of course, what would a check valve look like for a 2" radiator hose? Maybe the pump itself will act as a check valve. John Slade
