where the hell is this thing. i cant seem to find it. i know most cars have them right on the firewall, but not i said the cat. help? thanks

 

i think i am a retard and its right on top of the charcoal canister.

 

Well it Depends, what kind of car do you have and what year is it for me to tell you exactly where it is. Nevermind. Your Evap purge solenoid is located on your manifold. The canister has i believe either 2 or 3 hose leading to the intake manifold. One of the hose leads to this Black solenoid. that's where it is. Try looking underneath your Hood. By law there is a vacum diagram (for emission) It would show you where it is located.

 

incorrect. it does not show you where it is.. it shows you how the lines are routed..
