Evap or no evap that is the question.

Is it needed. Does it have any benefit or does it just add more pipe work to your intake!

[Dazzman1968]

You need it unfortunately, unless you have it taken out in an engine ecu remap, as the O2 sensors look for the EVAP "gas" input as part of their equation in how the car is running (lean or rich mixture)

I can take it out. I have efilive to do that.

But should I?

It's less offensive looking if you relocate the solenoid to the firewall.

Regardless of what you do...the tank needs some means of breathing.

Strictly speaking and to keep the hippies etc happy, this should not be to atmosphere. Although might be nice if it was down their throats lol.

Where can you get extended pipes?

I just used standard hose - the GM clippy connectors are a nicety, but a hose-clip should work fine. I think I had to unwrap the harness a bit, and I might have shortened it (memory failure). I'm away from home/car, so sorry I can't give you hose size...5/8" rings a bell. I went round refreshing the PCV hoses at the same time.
