Long story short I picked up a 73 Firebird Formula 400 that had a damaged Buick Quadrajet Carb on it. All the vacuum lines are wonky and not standard...so I have no baseline. I sourced a year correct Hot Air Choke Pontiac Quadrajet and am in process of installing. I need some help ensuring I connect the Vacuum hoses correctly.
All EGR and Emissions have been removed by the time I picked up the car. They just aren't there....
Only Vacuum Connections I "think" need to be connected are the following:
- Brake Booster (Currently connected to lower rear of Qjet)
- Line to firewall...which I assume is for HVAC (Currently Connected to top rear of QJet)
- Vacuum Advance on Pertronix HEI distributor (Currently connected on the lower front right of QJet)
- Vacuum Line to TH400 Transmission (????? - I planned to connect to same direct intake vacuum port use for brake booster w/ splitter)
I'll post pics tomorrow, but if anyone has quick feedback it would be appreciated.
