I seem to be missing one part of my APS extreme kit, it is a 9/16"JIC x 3/8"BSP adapter and it is used to return the coolant from the turbos back into the block. I have found numerous sources online but they are all outside of the US. Mostly austrailia and the UK

Anyone know where i can find one of these elusive doo hickeys

 

Did you try Earl's Indy down on gasoline ally? I have never gone down there without leaving with what I needed... They do have a lot of the wacky british pipe thread stuff and metric sizes.

 

try anplumbing.com

 

i havent been there yet, but ill try and stop by there this weekend. Its hard to get to indy easily since i live down in B town

 

BSP is tough to find. Ive purchased random ones from British American Transfer - http://www.batinc.net/main.htm

They are the MOCAL importers for the US.
