A Quick "what is this?"

3100, between the cylinder head and firewall. What connects to the thing on the left? I'm putting it back together and lost track of something. I've gotta be overlooking something obvious here. Sorry, photo came out a little blurred.

Photo's a bit blurry but looks to be a vaccum line connection.

That is the purge solenoid valve.

[garylau]

okay, but where the line that should connect to it on the left in the picture run to?

[tractorman]

There will be two lines that connect to the purge solenoid. There's a relatively small vacuum line that runs to the intake. And there's a larger line that runs from the vapor canister to the purge solenoid.

FYI, you don't want to leave this disconnected. It'll cause a strong gas-smell in hot weather. Left unrepaired for a long period of time, it'll ruin the activated charcoal in the canister.

BTDT.
