1975 124 Intake Manifold Sensors Needed Or Not

[Flyboytha1]

Hello guy's i've been having really good luck with super fast replys with great help & a great site for info:

Are these sensor being use in other 75" 124 spiders i'm in california but don't need smog cause it tops out at 1975 and lowwer

Anyways so what are the 2 bottom sensor used for and there's also one on top of the manifold if not need can i leave them be and not have to worry?

Also what is this 2 way brass tube there to the right there use for or go to or can it be simply plugged?

Thanks Much Again Guys!

On my 1975 I just removed or capped off the sensors as these are for the emission control system. The brass T is a vacuum port. One side connects to the brake booster. You can cap the other side off. Most auto parts stores carry a package of caps in various sizes. Depending on what carburetor you have you can also plug the others off or use one vacuum port for your carb's advance.
