All those carburetor connections! M4ME Quad. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone know or have a SIMPLE diagram as to what all the connections are on a quadrajet M4ME carb.? Very common carb. I hear. Sure would love to see a diagram showing them. Some are obvious,,,obviously.

The ones I know (I think) are the pcv, vac to dist., exhaust to charcoal canister, power brake booster and of course fuel line. I have three nipples blocked off. One in the upper rear, and the other two in front. There are three in the front, one is on the dist. vac. Those other two are blocked off. Does this sound like I have it right so far??? Thanks...

The Vacuum diagrams are usually on the emissions sticker that was put on the radiator support on the assembly line.
I haven't ever found a good comprehensive book of factory vacuum diagrams.
Try these from AutoZone...
