I’m 90% done with the engine swap on my 11 4.2 S5 bit I have a mystery plug I can’t find a home for and a question about the back side of the fuel system
Pic 1 1st plug out of the driver side harness inside the firewall.
Pic 2- does anything screw into this port on the back of the fuel system or is it for maintenance?
if someone knows or could snap a couple pics of these parts on their 4.2 I’d greatly appreciate it!!
