I've got a Romec AN style pump on my IO-320. I'm trying to figure out what all the ports are for. I get the inlet and the outlet that is pretty easy. There are four ports around the mounting flange. I'm assuming that these are for the overboard line. Basically pick the one that faces down and plug the rest, then tube it overboard to get rid of fuel if the seals start to leak.
The one that I can't figure out is the one coming out of the top cover of the pump. The pump I have has a small AN tubing fitting installed.
I'm also trying to figure out how to take a fuel pressure reading from this setup. Maybe that's what the mystery port is for?
