TWO hoses go from the canister to the carburetor. The "BOWL" or "VENT" line goes to the carburetor bowl vent fitting (near the top front of the carb). The "PURGE" line goes to a large-diameter fitting near the base of the carburetor. If your carburetor has only one large-diameter fitting near the base, it is a PCV (crankcase vent) fitting. You can "tee" into the PCV hose for your purge line in that case.

Dan, could I run a hose from the canister purge tube on the carberator and tee it into the PVC hose running to the valve cover? I'm running a 1945 holley. Didn't know if that's what were talking about in the above qoute.
Thanks

No, you wouldn't want to connect the purge tube on the carburetor to the PCV line. You could, however, run a hose from the purge tube on the canister to a "tee" inserted in the PCV line.

There needs to be a canister purge valve that only opens when the engine is above idle. Some canisters have these built in (looks like a round "flying saucer" atop the canister itself), but many do not, including Mopars after '72 and most late-model ones in which purging is controlled by the computer via a solenoid. Fortunately, standalone purge valves are readily available. NAPA Echlin # 2-28011:



Small fittings gets teed to the vacuum advance hose (which should have no vacuum at idle, full vacuum above idle)

Big fittings go inline with "PURGE" hose from canister to PCV hose.

The reason there's no purge valve on most of the Mopar canisters is that the "purge" port on the original-equipment carburetors were set up so as not to have vacuum at engine idle.

On most carbs the canister purge line goes to a fitting that is slightly above the throttle blades, when they are closed, so it won't cause idle problems. The PCV line goes to a fitting below the throttle blades.

Right now the hose from the carb purge tube is open. It's lapped over the valve cover hanging down towards the ground. I was wanting to eliminate this, to clean up the engine compartment a little.
