1987 Firebird Formula EFE TVS
I recently bought a 1987 Firebird Formula 305. This past weekend I had to rebuild the carburetor. While removing the vacuum lines, some of the hard plastic ones broke (as usual). Also one of the ports on the EFE TVS snapped off.
Is it safe to just bypass this switch or do I need to hunt for a replacement?

The worst capping it off would do is not closing the EFE valve when closed. If you can tolerate the slightly longer warm-up, no issues.
