Need picture of carburetor vacuum connections and what they connect to
Your distributor needs vacuum to advance your timing during acceleration. That's why you hook up your line to the port that has no vacuum at idle. :O)
Connect the line to a source that is above the throttle body on the carb. It should be a source that has no vacuum at idle.
what do you mean by TT impulse line hook-up??????
If it is a point type distributor you will want to hook it to constant vacuum...somewhere on a port in the base plate. If it's HEI you'll want to hook it to one in the carb body. Something that has no vacuum at idle but pulls vacuum as you give it throttle.
how do you hook up vacuum lines in a 1988 Chevy nova
engine vacuum or direct into the intake.
hook it up to the intake vacuum, normally the back of the carburetor where the brake booster may be plugged in. On a vehicle without power brakes, the vacuum port is normally plugged with a screw in plug.
The vac system has to hook up the the skimmer not the Hayward filter. k
It hooks up to the vacuum ports on the carb or intake.
Get manual specific to that vehicle and follow vacuum routings
There is no vacuum at the nipple on the EGR VALVE. The Vacuum line that hooks to it should suck your finger when you speed the engine up. That line will come from the TBI ( Throttle Body Injection housing) and hook to the EGR valve, and when the engine RPMs. go up it sucks the EGR VALVE OPEN. UNDERSTAND.
