I went all over town today and could only find the male barbed 1/8" npt fittings. I could not find the female to scerw onto it or a ballbearing or utility spring.

I'm trying to make the MBC in this link: http://www.c-speedracing.com/howto/mbc/mbc.php

 

Home Depot ownz you

 

are you sure they have the male and female barbed fittings?

 

Go to NAPA for brass fittings

 

yeah they have it

 

yea home depot or lowes is the cheapest. You can try Tacoma Screw if you are local.

 

I made one with 2 males and a coupler that came with my boost gauge, it works the same but gives you 2 ways to adjust it so you have a little more control over it. Be sure to use a stainless steel spring and bearing or it will rust and clog eventually.
