So on a boosted engine, I get rid of charcoal cannister, hook the vaccuum line from the check valve back up to the vaccuum port on the intake with another 1 way check valve to prevent boost from pushing back, how does that sound? But the charcoal cannister has a purge valve, I assume set to "purge" at a certain level of vaccuum/pressure...without it there, couldn't you also then still run into the problem of sucking the tank too hard when driving around in high vaccuum conditions (light cruise for example)?

Don't get me wrong, I will be venting to the atmosphere as you did in your writeup with a filter mounted up high and as far away from anything flammable, but it'd be even easier if you could literally just delete the cannister and hook up the vaccuum line from the tank back up to the engine.
