I just bought a march pump of ebay for $12. They are new and have a Krayton (sp?) housing. Rated for up to 200F temp and pump 3 gpm. Looks like they don't have threaded fittings though. Thought I'd give it a try though seeing as it's 1/10 the price of an 809 or other model. The item number is 150104625776 if anyone else is interested. There are a couple more.
