do not see emissions decal under hood. Only one sticker unless I’m missing something. Starting to think either this truck did not have it or someone before me removed wires.

will get all connected with what I have and see what happens. Just waiting for the fuel line to come in and can get installed back up in there.

do have another question regarding fuel tank, there are two fuel tank vent valves on top of the tank. Attached photo. What I’ve found online is that there is a hose connecting the two with a T connection in middle, where does that “T” connect to? I’m assuming the same line connecting to pump to evap canister in front? Not sure if I should start different thread on this? Thank you much in advance!

You should get to know that manual. You need to vacuum lines for the emissions.
