What is this box and why is the top wet with gas?

Parts cannon loaded.

Evap canister, Valve assembly and purge solenoid for $150 or so. Should be here next week.

May not need it all, but figured I'd go ahead and get it thinking it will solve my code and CEL issue. Stuff is likely original.

Why do they only sell the valve assembly WITH the metal bracket that holds it and the canister? The bracket is fine and I can't see why it would ever need to be replaced. Adds cost and requires a bigger box to ship in.


Lines are all OK as far as I can see. It's only the plastic nipple molded as part of the canister that broke off.

I did this exact thing about 4 years ago just last month got a leaking evap code, not a bad run.

If the EVAP cannister is saturated with gas the purge solenoid is not purging when your driving, it's supposed to trap the evaporating gas fumes when the vehicle is off; then use engine vacuum when the vehicle is running to draw those trapped fumes into the intake to burn them

It is possible the broken nipple is allowing the fumes to escape before going into the cannister, causing the appearance of raw fuel & the smell; but that should throw an EVAP code for a large or small leak as the vacuum will be too low within the EVAP system

That's what I was getting before all of this. I could reset it with a code reader, but it would come back a while later. I've probably reset it five or six times since I bought this vehicle.

I had no idea how to find the leak though and it ran fine. Maybe this was it all along.

.

I have a recurring P0442 code for 'small evaporative emissions system leak'. Auto stores will sometimes reset it for me, but they don't seem to want to and it just comes back after a couple of months. I don't know what causes it and don't have the money for a shop to fiddle with it for days to rty and find it. There are no operational problems that I can see. Runs and starts fine.
