I want to get rid of this HUGE charcoal canister monstrosity in my otherwise clean engine bay. From what I understand; this canister just purges vapors from the gas tank that would otherwise build up and have no where to go. It purges them back into the engine to burn, and pass emissions. What I want to know is how to ELIMINATE this successfully, while still being able to vent the gas tank vapors. Especially for applications that see POSITIVE manifold pressure, the canister would be working in reverse right?

Please only respond with USEFUL information, pics would be appreciated.

 

I know that plenty of you have info on this topic, I would like to discuss so I can understand better. Where y'all at? "y'all"

 

you are not from texas so you are not allowed to use ya'll

 

Stay on TOPIC: USEFUL information about purge canister elimination and function ONLY please. How does the purge canister work, exactly, how do I eliminate, will this cause problems?

 

all evap is mostly just EPA regulation, when you go standalone, you cna eliminate them completely, but removing the canister and all the lines as well as the check valves around the canister and gas tank.

there are about 2-3 multiple ways check valves around the gas tank, one on the canister and one soleniod on top of the intake manifold.

you'll just have to remove the line completely...the lines are ran next to the fuel feed and return line.

your fuel vapor will be released when you undo your gas cap to refill...so, it's not any different with or without EVAP canister.

Well the standalone is taken care of, I am just breaking the motor in with stock ecu, then the AEM goes on to tune!

And so you are saying, that I can just remove the firewall mounted solenoid, remove the canister, cap the vacuum port on the top of the throttle body that the purge canister went to, cap the other vacuum port on the Intake man. that the purge solenoid went to, then just follow the "purge line" that runs parallel to my fuel lines back to the gas tank, and remove the line as close to the gas tank as possible?

Will there be any check valves left? Have you done this, or someone you know personally?

when you trace the lines to the gas tank, you'll run into a few check valves before it goes in the tank.

open your helms, there's a diagram on the way the lines are routed as well as indicator which check valves is which...it is on the fuel section, it'll list all the evap components as well...

it's been a while, but you need to take off the plastic cover under the car that covers the piping from the gas cap to the tank, when you undo it, you'll the check vlaves...

I'd just leave the lines as it is if I were you...just take the evap solenoid from the IM and the canister out...and cap the purge line to the tank.

Any cons to just capping the purge line? I don't give a **** about emissions, so besides that, any cons? Has anyone else eliminated this canister in a different way, for any reason in particular? I just want to get the facts, and get this right, I will check my Helms for sure.

 

no, capping purge line won't do anything, again, the vapor will be released as you undo gas cap at fill up..

here's my suggestion, look at helms, study the flow and the diagrams of the EVAP function. See and try to understand why they put a check valve on a certain spot, then carfully map out eh flow direction, then make your decision. I did it.
