I don't know what to do here guys. I have read that the PEVR can be sent to TA performance for a new diaphragm. I also read about a PEVR mod using a 3 way check valve instead of original PEVR. Obviously the check valve would be the ultimate budget way to go and have a few here already. Which way should I go? I'm not even sure what the purpose of the PEVR is or if it's needed. I saved this link on the PEVR mod (3 way valve) but having a hard time figuring out the line routing . https://www.turbobuicks.com/forums/quot;before-black-quot;/25498-new-pevr-mod.html The one that says to carb power valve. The stock Q Jet has a power valve? Help me out here guys
