Who has deleted their Evap return system? I did a little reading and it seems I would need to install a filter at the carbon canister or at some point just to keep dirt out and I can just do away with the solenoid on the intake and the second line under the hood. I tried searching but to no avail.

Maybe this is uncharted territorry for the V crowd. I don't really have a reason to get rid of it other than that it is kind of ungly crossing my intake. Has anyone come up with alternate routing that looks a little nicer?

Are you looking to delete the PCV?

Evap delete, not pcv.

If I recall correctly the evap has a sensor on it which might need to be turned off. Curious to see how this works out.

I will have to turn off the error reporting.

The PCV system is critical and i would never delete it. The evap to my understanding vents excess pressure in the fuel tank and that the line coming from it needs to remain open to the atmosphere to vent the fuel tank. I probably need some kind of roll over valve/one way check valve to install in place of the solenoid.

Not a good idea with ethonal blended fuel that we have everywhere.

I thought the evap just bled off pressure and vapors from the fuel tank into the intake to be burned. I don't know what ethanol would have to do with that. My 1970 Elcamino SS vents to the atmosphere no problemo.

Phase separation.

Long story short, alcohol absorbs moisture...once this occurs, the various components of the fuel are no longer a homogeneous mixture. The alcohol which serves as an octane additive (not to mention the whole host of other additive's that are affected) no longer serve their intended purpose. Granted, if you maintain a fresh tank of fuel in the car every time you drive it (or have access to ethanol free fuel, known as "E0") you may never notice a difference.

Otherwise, you're only hurting yourself.

I go through a tank a week. Could that much alcohol evaporate through a 3/8th inch hole? I don't know that I am stuck on getting rid of it but I would at least make it look a little better.

I reread the article and I guess it is saying that the alcohol draws moisture and evaporates which in turn lowers octane. We have 93 octane fuel with less than 10% ethanol (supposedly)

You have to remember that you are the end user, and the fuel that you fill in your tank could have already absorbed 9/10th's of the required moisture in order to cause phase separation through the normal supply chain.

If you re-read the article in the link you will find that the degradation of the fuels octane rating is only one of the detriments. Ethanol is corrosive to many materials, and can also expedite electrolysis in dissimilar metals. It's no stretch of the imagination to theorize that the fuel pump (or anything else in the entire fuel system) could suffer substantial wear over a very short period of time.

I'm not sure that I've ever seen a "sexy" EVAP system, but if that's what your after it's probably in your best interest to get some braided line.

Ok, you make a good point. I have a Matercool flaring kit (it does push connect flares) so I can make part of it out of steel or aluminum tubing and connectors to connect -6 line to it. I was already considering the braided line. THanks for taking the time to post the link to actually explain why not to delete the evap system.
