Why is this missing ?
I bought a parts truck the same year as mine (1999 dodge ram 1500 5.9 v8 4x4) only difference is that its 2wd. I was pulling some parts and noticed a part that I don’t have in my truck. Unsure of what it is or if I need it in my truck. It’s located front right passenger side.
my question is what is It and do I need it.

Why bother? It produces a small amount of pressure in the gas tank then it monitors it to see if there is a leak. If there is you get a cel. I would imagine the pcm would have to be updated for it also. I would think there is more you don't see under the truck since the ones without it are different.

I do believe, that while that's the evap valve, you're gonna discover that you need it for the factory system to work correctly. It uses engine vacuum to suck out the gas fumes from the tank as you drive along. In fact, you can hear it click under normal engine operation. If not for the valve being hooked up to the gas tasnk, the tank would swell and begin to leak, for the want of the pressurized tank looking to relieve the pressure.
