Vacuum canister question...... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just installed a vacuum canister to help out with my power brakes.
I noticed that when after I cut the motor off it still holds vacuum. Is that normal?

bryanw1968 Do you have any pictures of your Vacuum canister installed I have one on my truck but I haven't hooked it up Im still looking for ideas of where to put it or maybe buying a different one as I think its too far. I mounted it on the fender near the rad support with a blazer charcoal canister mount.

Petey, Even though I was not asked, I mounted my vacuum canister just under the master cylinder slightly toward the engine on the inner fender. The vacuum lines travel nicely from behind the carb, to the vacuum canister and then on to the booster.
