I believe the solenoid is stuck open only slightly. I tried closing the vent solenoid while the system was purging afterwards and it did draw a vacuum on the tank. I agree that it should have if the solenoid was leaking. I'll post a follow-up if and when I replace the part.
Thank you , Phil. Every video is 👍🏼👍🏼. I hope you had a nice weekend.
That doesn't seem to explain the tank not building vacuum though? Or I'm confused, which is more likely.
