Question about boost in EVAP system?
I was reading an article the other day and it was talking about the install on the HKS supercharger on a 350Z. They use a one way check valve on the EVAP system vacum line. My guess is to stop excessive positive pressure from getting in there causing havoc. Should I have a one way check valve on this line for my EVAP system? It really can't hurt anything I would think. dunno.gif

Ideally you would have good quality one way valves on everything that relies on good vac source to work right. This would be the PCV, Brake and Fuel Tank EVAP line.

Don't have to worry about the brake vacuum. They have check valves from the factory. You might need to upgrade it if you start running 25 to 30 psi though.

Unless your like me and tossed your stock brake booster line forgetting it had a valve in it. Now I just use an inline PCV valve and it works great!
