Prestolite trim pumps
 
I have these Prestolite trim pumps for my Kiekaufer tabs. How do I know which port is the high pressure port.

Hook up the pump, activate the solenoid with the blue wire, the port that squirts is it.

Never had to mess with mine but I'd think the pump is reversible, so 1 port is press and the other is return going UP and everything reverses going DOWN.

Thanks. Figured it out. The port coming out of the bottom is the high pressure.
