Question:
As attached by the factory to the OEM Lycoming, what is the (circled) fitting to be used for?


 
Usually fuel pressure sensor. It can be capped. Best to do the insert cap directly to the divider as opposed to capping that fitting.
Best,
 
That port is for your back up fuel supply from the back up throttle body. If you aren't using a back up system just cap it off.
 
Thanks Guys,

Just underneath the fitting the word "GAGE" is engraved into the divider. I removed the fitting (shown) and will cap off using a pipe plug.
