Thanks Alvin. I buy a lot from Inline Tube as they have a great ebay presence. I can't hardly stand to buy from them through their regular website since they don't have an interactive catalog or search function, but on ebay they have a lot of parts listed and pretty good search capabilities if you go their store.
More on the repop waterneck from our sponsor...
So I thought the repop waterneck was bad before I got the nearly pristine old one from ebay.
Here's a couple pictures that show old and repop side by side. I tried my best to align them accurately. Note the difference in the angle, height and flared end.
