I put a vacuum gauge on the tank side of the purge valve, and it does not pull vacuum until I rev the motor. Or if I let it sit for 5mins or so it will pull the same amount as revving, which is 20 pounds. Is that the correct operating peramiter for the purge valve? Has anyone had this before? And what did they do?

Also, after replacing the gasket and gas cap, the light came back on around half a tank after a full fill up. ALSO, my gas light blinks as well randomly. Even when half full. When the check engine light came back on, the gas light started blinking immediately.

Any recommendations on a next step? Any input is greatly appreciated, thanks!
