LESSON LEARNED

If you are installing a SMIM, and your stock brake booster line does not fit, do some research before just adding some 3/8" hose. There's a friggin check valve inside the OEM vacuum line that goes easily un-noticed. I've been boosting into my brake booster for the last few weeks now and couldn't figure out where this boost leak was coming from. I feel like an idiot, and just figured I'd warn anyone else out there reading this, so they don't do what I did.

Thank god I just happened to have a bunch of extra 3/8" check valves sitting at home randomly from when I did my Catch Can setup!
