Below intake driver side USA version, L shaped pipe with threaded end. What is this, what connects to it?

 

don't have the Rave opened in front of me, but is that the Schrader valve for the fuel rail?

 

I think that was what he was asking about. That's the pressure test port on the fuel rail. Should have a cap on it but other than that only used for testing fuel pressure or draining pressure when removing injectors.

 

Oooof seeing those coil packs back there give me PTSD. So thankful I went with the relocation kit.

 

lol it really does... i'm installing new Bosch coilpacks and sealing her up ha

 

Great! thank you...
