Hello and welcome to Just answer,
GM has a service procedure upon vent valve replacement a new filter is added and relocated, this should come with the valve you have if not the filter kit is recommended. The gas tank does not need to be dropped.
Below is the part number and service bulletin with pictures that show what needs to be done
19207763 (2004-2009 Model Year)
Solenoid Kit, EVAP Emission Canister Vent Valve

Evaporative Emission Canister Vent Solenoid Valve Replacement (Extended Cab)
The filter box opening should be pointing downward.
Does this help if not let me know? find the charcaol canister and look for the large hose leaving this leads to the vent valve
cant see anythging on the sises of the gas tank found the big box but cant find #2 in your picture
On the charcoal canister (big box) there are 3 lines or hoses, 2 will be close together and one will be off by itself, it should be the largest hose on the canister, follow this hose to the valve.
This should be the location of the valve. towards the rear of the tank.
last thing i hope,after i take this off will i have enough room to relocate and disconnect it
to run hose
Yes once you get the bolt out, it should move out so you can disconnect it.
Do you have the kit I listed in the first post?
i bought part(NNN) NNN-NNNN/p>
gm 19207763,looks like it but is non electrical and one part looks exactly like tthe vent to be now on the top of tranny
The vent valve should be electrical and the filter assy is the piece that is placed up on the tranny vent, You will need some 5/8' heater hose and 4 clamps to fit.
That is the correct number but it should have an electric vent valve inside.
You still have the link to the post on ebay?
Does what you have look like the picture on the Ebay page?
Okay I think you got the right part but you dont have the filter kit.
You can replace just the valve if the vent hose is not clogged, which is the other hose on the valve not leading to the canister.
The "kit" part number 19207763, comes with the filter and vent valve, you then need to purchase about 5 feet of 5/8' heater hose and 4 clamps to perform the bulletin.
The part sold on ebay was probably old stock from a dealer that was updated with the new kit and was only the valve.
The filter and hose relocates the inlet to the vent valve to a better location so water, mud and dirt does not get ingested into the valve causing it to leak or stick open.
Good, now you just need to get the heater hose and clamps, and a tie strap or two.
