My new CHEAP manual boost control valve

I like building what I can, and for 10 bucks I'd never be able to buy the material to make one so I figure modify to make it the way i want it. As for the hose blowing off, the hose was old and needed replaced anyway.

Here is the update on the boost controller

I'm still working on getting the spring pressure just right. I may have to shim the spring some or get a longer spring. It wasn't hard to do and took about 1 1/2 hours trying to take pictures.
