Default Onan MCCK Spec F Raw water pump ports

How do you tell which port is the intake on Onan 131-0165 pump? The pump is off the generator. The bracket allows the pump to be mounted two ways. I can't find any markings at either port. A picture would really help.
Thanks

If the pump is the same as a Spec C then the inlet is inline with the "Onan" cast into the body, it goes approx 11 oclock looking at the flywheel side. . The discharge goes straight down. Cheers Dan

Thanks.
If I could only get it to pump water. I bought what was advertised as a Onan OEM impeller and I received Globe-blue impeller. Still waiting on Marine Discounters to resolve the issue.

Ya the Onan impellers are quite a bit wider than the standard Jabsco ones. I dont know if I have any more new oem ones. Cheers Dan
