Vacuum Canister to Restore Vacuum - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**KyleSeal** · 08-23-2016, 10:01 PM

454 bored 30 over with a Comp Cams Big Mutha Thumpr. Called them and they said its gonna barley have any vacuum. I was told a vacuum canister can solve this because my power valve and vacuum secondaries are being used at idle because of the low vacuum, causing it to be very rich.

So my question is are there any ways to run a vacuum canister that can boost vacuum to help my carburetor run better? I see people run them for brakes. I have hydra boost so I have no need to route for brakes. Just need to route to create better vacuum to have a better running carburetor. Is this a viable idea?
