I'm getting ready to hang my O-320 this weekend and trying to tie up the loose ends. I think I've gotten everything done on the firewall and the proper fittings on the accy case. Thanks to the guys for the "Illustrated Engine Hanging" article on this site. Anyway, after looking at Van's FWF drawings at the engine driven fuel pump, mine seems to be a little different than the one depicted on the drawings. It came from my engine builder for a carbed engine.
I know the two opposing connections are inlet and outlet, am I correct to assume the the small 1/8" NPT fitting is for fuel pressure measurment?
