Hi gang...have not been around in a while but finally getting around to doing some work on my son's 67. We have removed the FAST EFI system installed by the PO...returning the car to as close to stock configuration as we can.
So we re-installed the mecahnical fuel pump which was still in the trunk of the car...looks like an Airtex or something...there is a 3/8 nipple for the inlet...an inverted flare fitting for the hard line to supply the carb...and a mysterious (to me) 3rd nipple or port..smaller size like 1/4"...
Can somebody tell me the purpose/function of this...where does it normally run to? ...can we just plug it off?
