I'm looking for a part number or a place online that might sell it!

I'm looking for the air bypass valve, PCV valve, or whatever its called that goes in the Brake booster vacuum supple line!
I cant seem to find this ANYWHERE, mainly because I don't know the correct name for it!
But I had to replace that vacuum line and didn't think to take the old one out, so i tossed it and realized it leaks through the brake booster and at full boost if you go to hit the brakes there is not control for a sec or two(till boost pressure drops back down to vacuum) which is, in my eyes, a safety hazard!

thanks in advance!
 
Yep i got mine a the junk yard, or the dealership, someone parting a car out, laser, eclipse, talon same non turbo or turbo will fit. Online i doubt you will find that line though, try jnz auto they might be able to get it is a oem part.
 
I got some one way check valves online, for like $4 each. I'd have to do some digging around to find the exact source and p/n's, but they do exist. Just not the specific one located within the brake booster line. Just grab another line from one of the above mentioned sources.
 
There's a difference in the hoses. The turbo application has a check valve built into it. Stops boost from entering it. Hopefully you didn't blow out the brake booster running a hose w/o the check valve. Check the stealership or NAPA for the correct hose.

Mitsu CAPS doesn't differentiate between turbo/non-turbo when looking up that brake booster hose, which leads me to believe they are the same for both models.

It takes a good bit or just luck to blow it out. I've ran 25psi through the booster (not sure if it was a 16g or if it was the HX40) until I realized that line got replaced with a regular hose. Didn't find out until a boost leak test a few weeks later. Still works fine now.
 
Sorry for the late response, but thank you, thank you for the help! Ill check all the linked resources and see what I can come up with, non the less all of you were a great help!
