AST replacement with a difference
I have searched and read and decided that I am going to do this mod , but I am st ill uncomfortable with replacing one piece of plastic with another , since the replacement part is also made of plastic . Has anyone tried other means such as ...
1 . Modifying the stock piece by drilling a hole and welding in an aluminum tube / fitting to accept the overflow hose , or
2 . Fitting a whole aluminum piece like the ones sold by JEGS.

don't race, don't need to
He means AST elimination, whereby you replace the aluminum filler cap stand on the older style water pump housings with a plastic peice from an FC that allows a pressure cap to be used there. You then run the outlet from the plastic replacement to the overflow tank. He wants to use a metal stand replacement instead.
If you have a newer water pump housing, then you don't know what I'm talking about because those are all one peice. To eliminate the AST on those systems, you must drill a hole in between the top of the neck and the land where a pressure cap would seat, then put a nipple into the hole.
To answer your question Marcel, I don't think many of us were aware of the metal replacements you show above, and just use the plastic FC part 'cause that's the one we know about Give it a try, and let us know how it works, ok?
