1977 280z Throttle Body Connections

lpklem · Jan 8, 2015

Just rebuilt the top of the motor and I'm having difficulty with connecting the two vacuum lines out of the throttle body, one I assume goes to the "T" connector the other is a mystery, any advice please, would be appreciated!

Thanks in advance. Larry

Your assumption is correct. One of them goes to the "T" that feeds ported vacuum to the distributor and the carbon canister. It's item #14 on page ET-2 of the 77 FSM.

The other nipple feeds the TVV for the EGR system. It's item #22 on page ET-2 of the 77 FSM.
