I was getting a P0304 Code (Misfire #4) so I removed the sparkplug wire from #4 to check it and the plug. In the process, DUMB*** me knocked one of the vacuum lines off the evap switch. I have searched and can't find it and none of the vac line diagrams that I have been able to pull up show 3 line on the evap switch (only 2). Can anybody give me a diagram with 3 vac lines on the evap switch or tell me where the ines go from the switch? Thanks

if you knocked one line off put it back where it came from?

I wish it was that easy! As I said in the post, I knocked it off and now I can't find it. If I could just plug it back in I wouldn't be asking for a diagram.

oh, it dropped down on top of your exhaust manifold then. educated guess, mine wound up there once lol

I've checked that area many times already but I'll go check again. Be right back
09-14-2016
what side you looking for? the engine side or the other side that leads off under the master cylinder?
09-14-2016
mine had a white pinch clip on the end, you see it to the left of the red tranny dip stick. mt evap is deleted so its just hanging out back there.

this is the engine side, starts at the tb loops over the top to a hard line tot he evap.

I checked that area again and still no luck. The lines that are still connected go to the evap canister purge valve and to the evap canister. Any idea where the third one is supposed to go?

this is a 97

I have that diagram but it only shows 2 lines off the evap switch and mine has 3

post some pics of your set up.

This is my evap switch. As you can see there are2 hoses attached yo it and one open fitting. That's the one I can't find.

Don't know why but the photo came across upside down. The nipple is actually on the bottom of the swich pointing down towards the valve cover
09-14-2016
im thinking its not a nipple at all. start the car, see if theres any vacuum pulling or pushing from it.

I'll do that but I know I knocked a hose off it.

As soon as I fire it up, it pops a P0171 code now. Having read more than one post about that code I know I've got a vacuum leak that I didn't have before I knocked the hose off.

pull out more with the camera so we can see the evap purge solenoid too. those two get linked together.
09-14-2016
it has a hose that goes to the evap purge solenoid and it's connected

Where does the tee'd hose that runs under the battery and then back towards the firewall go? I know that the other side of the tee goes to a vacuum bulb in the driver side fender but I can't trace the other part of the tee. I'm wondering if that's the one that I knocked off and should be supplying vacuum to the evap switch. I'm just asking because I don't have a clue
