So I get a new charcoal canister with surge valve attached as the

delivery I put it in , power it up at idle and test it at the purge
port with my hand vacuum pump. WELL I could get it up to 15" but
it would leak down in less in than ten seconds to zero while powered.
Make that 5 seconds. I bring it back in and say it's defective. now

the charcoal canister. I just took mine out of the loop
