Gas tank vacuum vent w/ carbon filter box - remove?? July 12, 2013, 04:51:57 PM I'm putting my 3.8 back in my car, and I'm wondering what the purpose is of this big box hanging around. I originally thought it was venting fumes from the tank into the intake for a little bit of a richer burn, but apparently this carbon filter is removing all the fumes. Is there any reason to keep this here? Could I bypass the box and put the gas fumes directly to the intake, or just take it all out and lave an open breather on the fuel tank? Quote Selected
Gas tank vacuum vent w/ carbon filter box - remove?? Reply #1 – July 12, 2013, 07:07:33 PM Leave the charcoal canister as is. DO NOT REMOVE IT AND PIPE IT TO THE INTAKE!!! If not leave it out and vent to atmosphere. But it is better to leave in in place as the purge cycle will richen up the mid range and it is beneficial. Quote Selected

Gas tank vacuum vent w/ carbon filter box - remove?? Reply #7 – July 13, 2013, 10:19:56 PM Well that wouldn't be too bad I guess, having a bit of gas smell. I guess capping off the breather is not a good idea? Quote Selected
Gas tank vacuum vent w/ carbon filter box - remove?? Reply #8 – July 13, 2013, 11:44:52 PM I think most posting on this issue do not know how this system WORKS. 1 It stores HC gas fumes by exorbing it. CHARCOAL app the equivalent of 2-3 ACRES2 when the engine sucks the fumes out of the canister(PURGES IT) it makes the mid range a little richer.3 It keeps the car from smelling like GAS4 It keeps tuns of Hydro Carbons out of the atmosphere. That"s a good thing dont you think!! Quote Selected

Gas tank vacuum vent w/ carbon filter box - remove?? Reply #10 – July 14, 2013, 02:32:52 AM makes the mix a little richer, so you mean the carbon filter doesn't filter out ALL the gas? And I know not all cars have a system like this, that's why I was asking if it would be a bad idea to cap the vent off Quote Selected
