Default What is this???

What is this thing attached to the manifold? the thing with the yellow cap on it and the line off of it? And mostly, do I need it? I am swaping this engine into my GN and found there are a few things I can delete off of the motor.

EVAP system solenoid. It connects to the line that runs all the way back near the fuel filler in the rear fender on an Fbody to a charcoal canister. It is emissions equipment.

Yup, it purges gasoline vapors from the tank through the intake to be burned.

Many who delete this sometime have issues with filling the tank because of pressure.

I wouldn't delete it, just relocate it. I relocated mine behind the inner fender down where the fuse boxes are. You just have to extend the wires and run some new hoses. It is pretty simple. However if you are putting it into another vehicle it might just be easier to remove it? Not sure if the GNs have a evap system from factory?
