Gas Leak out of 6 Port- Dash Switch the Culprit?

[44SAA]

I was under the dash and while there figured it was a good time to replace the RH/LH switch on the dash. The driver side tank has never worked so I though it was worth a shot. Well, short version is now gas leaking out of the pollack valve, specifically what appears to be a 3” rubber breather valve. I also noticed significant pressure in my fuel tank as i unscrewed the gas cap. I understand I’d have better luck sourcing unicorn tears than finding a 1980 pollack valve. Does anyone feel re-installing the old broken dash switch will stop the leak?
