Also, just one afterthought. In this original post, you stated that we "sent you the incorrect part" The description of this item clearly lists the heater hose nipples as featuring 3/8" NPT threads. We sent you exactly what was listed in the description of the item. Just because the water pump housing you have uses a different size, doesn't mean we sent you the wrong part, it means you didn't read the description when purchasing the item, or look at your water pump housing to determine if they would fit properly before ordering. And then you come onto a public forum and make a thread titled "440 Source sucks" because of that. No way do we deserve that.
