there is a arrow on the pump itself to tell you the direction of fuel

you cant tell just by looking at the fmu. You actually have to disassemble the unit to tell where it is. I dont think they were smart enough to write "in" and "out" on it.

I will go look at the bare unit tomorrow and tell you which one is which. I have the original CAD drawings on my old laptop. I have to set it up to display to a TV screen since the monitor went out.
