Kurt Posted April 18, 2020 Report Share Posted April 18, 2020 Where can you buy the charcoal filter that goes on the bottom of the carbon canister? Can you clean the entire canister my immersing it into something? Quote Link to comment
datzenmike Posted April 18, 2020 Report Share Posted April 18, 2020 There is a thin fiberglass? filter on the bottom but there only to hold the activated charcoal from falling out I think. You could cut one from a thin piece of pink insulation or support the old one with some fly screen. For the charcoal just get any canister from any car and empty it out. You could try the Nissan dealer or an auto supply. The part number for the bottom screen is 14952-N5300 about $10 at the dealer (doubtful) probably half that elsewhere. Quote Link to comment
Kurt Posted April 18, 2020 Author Report Share Posted April 18, 2020 Thanks for that. Can the entire canister be immersed in something to clean it? The canister doesn't open up but it must be foul and in need of some kind of cleaning. Quote Link to comment
datzenmike Posted April 18, 2020 Report Share Posted April 18, 2020 The charcoal only stores gas fumes. When the engine is running fresh air is sucked in through the filter in the bottom, displacing the fumes out the top and into the intake manifold. I suppose the bottom filter could be rinsed out or replaced but there's nothing to plug the charcoal granules. I wouldn't mess with it and risk ruining the charcoal's absorption quality. Basically don't try to fix what isn't broken. 1 Quote Link to comment
Kurt Posted April 19, 2020 Author Report Share Posted April 19, 2020 Great scoop. Will follow your guidance. Why/how do you know so much about Datsun B210s? Quote Link to comment

Basically don't try to fix what isn't broken. O'Reiley's used to sell replacement lower cannister filter pads. You just removed the old filter and slapped on the replacement. Don't know if such a low level of sales unit survived the bean counters but give it a try. These purge cannisters are usually located low in the engine compartment so the filter is subject to trying to inhale road crud, thus the external filter medium. Quote Link to comment
