vapor canister for LS swap

[LeesTruk]

I want to hook up the vapor canister when I install the 5.3L in my '80 C10. The original many port canister is "dead", having puked most of its' fuel contaminated charcoal onto the radiator support. I'd like to use a later model 2 port canister and was wondering if I ran the canister purge line to the air filter box (stock filter box from '05 Tahoe) there would be enough of a vacuum draw to actually pull the fuel vapors into the intake. My PCM has been reflashed to eliminate the evaporative system, and my harness has no wiring capability for a purge valve. Any thoughts? Thanks
