Default Evap System.

Hello everyone.

I'm looking for a diagram of the evap system for a 98 vette. Does anyone have a diagram?

Thank you!
Constantine.

Nobody has a diagram? I've Googled it, but can't seem to find a diagram. I see the solenoid, and valve. The valve has some other vacuum hook ups, but they're not hooked up to anything. I'd like to see how it's supposed to be hooked up properly.

A diagram would be really helpful.

Thanks.

the hose connects to a fitting at the firewall (from the gas tank)(drivers side) and the front of the solenoid goes to the throttle body.

Thank you for the replies.

Here's what I'm looking at under the hood. (Well, pulled out now so I could take a pic).

I see the evap solenoid and the line that runs to it, then to the throttle body. On the back side of the solenoid the line runs back and into the firewall.

Tee'd into the line is this switch. The elbow on the left is where it tee's into the evap line. However, where does the elbow on the right hook into? Where does the other port underneath that in the picture go to also (the bigger one with the flange)?

Another thread brought back from the dead... BTW, you do realize the OP has a C4 now?
