intake manifold for vacuum headlights....

[1974dodgecharger]

I have a canistor, but my carb does not have an intake vaccum.  If I wanted to could I take out my manifold, drill a hole, tap it, and connect to the canister to get my headlights to work?

Or get a different fitting T with a second port nipple , the one where your power booster hose gets its vacuum

Yes, this is how my car is set up.  The brake booster's check valve has two fittings on it: one that goes to the manifold, and the other that runs out to the headlight doors; mine are currently disconnected, though...

actually my carb does not even have that it has no ports except the nipple port to test for timing to the dist.  Thats it....found out its a race carb.

Yes, my 'carb has fittings for vacuum but I don't use them; I run vacuum off of my brake booster...

You need the fitting with 2 nipples that is located behind the carb, threaded in the intake manifold.

Ill drill it back there then on the manifold or if my newer carb has a one spot I wont...looking to buy a used 850 DP this weekend, maybe.

you need a vacuum source from the manifold, not the carb
