hi to all, i have a question about connecting a 4 bbl q-jet. on my 71 skylark i changed my 2 bbl intake to the stock 4 bbl intake with the stock q-jet. may be you guys can help me to connect the vacuum lines to the carb. pls see the numbers on the pics. am i right that: number 3 (the little tube is missing, i replaced it) is ported vac and should be connected to the distributor? number 1 should be connected to the hose on the backside of the intake. where to connect number 2 (i think it is full vac!?) and number 4 ? would be great to get some help greetings from germany oliver
Yes #3 is ported and can be used for vacuum advance on the dist. That is where I have it hooked up. Others hook manifold vacuum to the dist. Yes #1 hooks to the rubber hose attached to the PCV valve in the back of the intake. #2 is manifold vacuum and can be used for your evap system, if equipped. #4 is manifold vacuum, could be a good place to tap for the distributor vac advance if you want manifold vacuum. Put rubber caps on anything you dont use.
