The PCM uses backpressure readings for fuel management, especially if you are running a chip. I would buy a new tube and replace it if it were me.

It should be on, it does not HAVE to be on... Just to be clear.

When mine broke I did a "quick fix" with a brake line. It's been there for four years now. Thanks for reminding me.
