I want to remove the evap system from my 99 prelude. She is running an s300 hondata so I am not worried about codes. My concern is the gas tank ventilation. I don't want to vent gas vapors into my engine bay or lose most of my fuel to the atmosphere. For those out there that have removed the evap, how did you solve the problem? Should I just plug is and use a vented gas cap?

 

bump. I know I'm not the only one that has removed an evap system.

 

I've just run the ventilation open to the atmosphere in my engine bay. I'm not concerned about loosing my gas as vapor, i have no proof, but i doubt you loose too much. Probably wouldn't even notice the difference. I don't even thing you will get any codes, but not 100%. I didn't with obd0.

Just run the line to the ground, unless your concerned with the environment or something. Avoid exhaust.

 

I just left my line in the bay open too, I am unaware of any issues in doing so.

 

obd2 would throw a code but he has hondata so no issue anyways....just bend the line downward out of the bay if your concerned
