So I have been searching under ever possible title for the do it yourself boost valve and have had no luck finding anything. I saw a post where the member actually made a shopping list of the needed materials. It was the type where he used brass fittings I believe and used a setscrew and spring with a ball setup to adjust the pressure on the spring. Can anyone point me in the right direction? Thanks guys.

Hope this helps...
