As to Charcoal dust clogging the N-80:
I would suggest you add a filter just before (to drivers left of N-80). NAPA PART 3002 fits well. Duane came up with this years ago. Simply cut out a very small section of hose- about an inch & a half to two inches - and insert the filter. There are many old style gas filters that do the job. Works great to avoid the charcoal dust from the canister from clogging the N-80. ?Simple and cheap, and readily available, and you can see into the filter- replace when it is obviously dirty. Happy Trails.
