Vent solenoid location

[liftlawssuck]

2006 GMC Sierra 1500. Looking for the location of the vent solenoid. The place where I thought it would be has nothing that looks like it. Also I might not have the right part as it listed 2 different part numbers. So I'm not sure which one is there. Anybody run into this before?

Thanks

Assuming you mean the Evap vent valve.
It's on the rear of the fuel tank on my 2005 2500HD.
The Vent filter should be along the LH side of the transmission if the TSB has been performed.

Evap vent looks something like this on my 06 GMC.

The failure on mine was the filter itself filled up with dirt. I work in a dirt/gravel site so dust is terrible. I found the filter was full of it.

You can just clean the crud otta that filter. The open cell foam is basically the same stuff as a Wall AC air filter.

Yea I have the part and have replaced many of them. Just can't find the damn thing. I think I have to do some more digging. But thanks for the tips.

Some are at the rear of the fuel tank. Some are mounted on the crossmember near where the filler hose meets the tank.

Edit, here's some pics:

This is great!! Thanks. Mines certainly not like the first pic. The second is almost what I have. The EVAP canister in laying horizontal on mine. I haven't seen any other pics on the web like how mine is. But none the less it's most likely located on top.

Once I locate it the questions is...drop the tank or pull the bed??

Dropping the tank is a colossal pain the the gluteus maximus. Not to mention the fact that dropping the tank disturbs a lot of stuff that's far better not disturbed.

Pull the bed. DO NOT USE an IMPACT GUN!!! It'll break the sheet metal cages around the captive nuts. Put Never Sieze on the bolts and inside the threads on the captive nuts when you re-install the bed.

I've had both the bed off and tank out before but being from New England it looks like I never had them out. As far as Never Seize, when I'm done I usually look like the tin man from Wizard of Oz I have so much on me.

I have changed them without doing either. I stick my hand up behind the cab and then go on top of the frame rail. It’s held in with a tension clip.

I actually recently replaced the tank pressure sensor without pulling the bed or tank.
Reached between the bed and the frame and did it by blind feel. Thankfully there wasn't much dirt but I loosened what dirt there was with my fingers and blew it out with a backpack leaf blower.
Nasty job but easier than pulling the bed or the tank. I was told by a mechanic that wasn't possible... after I'd already done it. Here's your sign.

I changed my 06 silverado 4wd quite a while back . I did not remember it being a problem . Seems like it took like maybe a hour .

What I do remember is the kit they wanted me to put was expensive . I did not use the kit and found out there was another valve that fit perfect with no problem and was less than 1/4 of the price . The kit comes with a hose and filter and they want you to run it to the front of the trans . I can change it several times if needed , But it has been fine for years .

Just don't over fill the tank . When the nozzle clicks stop . If you give it more above that it will over fill and run into the solenoid and damage it . I was bad to do that .

Just a little piece of info if anyone was interested .

I did the same thing. What I was told is GM updated the solenoid for the trucks, but not the Tahoe and Suburban. I bought a solenoid for a Tahoe when my Silverado's original went out after 10 years. Direct swap. If the new one lasts another 10 years, I'll be happy.

So took another look at it to find this piece and I cannot locate this to save my life. Looked on top of tank with mirror and nothing. Looked all around and can't find it. Although I did find my shock mount broken in rear!!

I would think your 06 gmc would be the same as my 06 silverado . Look about center of the truck and center of the gas tank . You will see a square looking box which is a charcoal filter . There will be a hard plastic line coming off the rear of it . This line goes to the solenoid to the rear top of the tank . It is a quick release . Look at the second picture above . You can see the square looking box . Follow that tube back to it .

Mine was on the front and to the inside of the fuel tank. Manual trans trucks use a different hose assembly. Usually you can pop the cover off and clean the filter.
If you replace it, just cut the rigid plastic tube it connects to and use a piece of hose to splice the new one onto the plastic tube..
