Thread: Deleting the EVAP

I have been thinking about deleting the EVAP on my car while it is apart. I would do this mostly to clean the engine bay up but is there any other advantages of this. Also if you did this how did you go about doing it?

I know for one that I'll be watching this as well as I have considered deleting the EVAP as well and the EGR after seeing the inside of my LIM.

My EVAP is disabled and blocked off under the car. Same for Keifer.

How does one go about doing this? Did you remove the solenoid and such as well?

Just unplug everthing and toss it I left the vacuum line from the rear open near the brake resevoir no problems.

Exactly. Remove the codes and trash the plastic crap.....I just decided to block ine off because I was afraid of anything getting in there. I hear it's not needed to block it off though, just remove codes and electronics.

Are there any downsides to doing this?

I don't think so. It is never open when the car is at operating temp. I believe it is only there to remove the fumes from the tank. Just some more emissions garbage.

I've thought about this too. You would definitely still need to allow venting of the gas tank, so under the hood is fine?. The other end of the soleniod connects to the TB. You would have to cap that off as well, yes?

Thats why I plugged it. It's easier to just pull the gas cap every once in a while.

Could you not just cut the tube near the tank and leave that open to vent the fumes?

I've heard if you park in a garage, you will start to smell gas after a while.

If the line was unhooked somewhere around the tank, would there be any concern, about fumes pooling and a spark setting it off? When I was a kid, one of my good friends and my little brother were both severely burned in separate gas fires. My brother, the actual flaming liquid (I saw that one) and my friend, it was ignited fumes that engulfed him. When it comes to gas and potential problems, past experiences have left their mark.

Do they make vented gas caps for our cars?

Even better question. I thought they were all vented but I never knew for sure.

Nope, normal operation the tank has to hold a vacuum. Ever fill gas and not get the gas cap on all the way, it will set the SES light.
