My 245 Oil Pump has a hole in the pedestal top plate for conduit.
It is a different plate than the 241, and the top cast piece has threads for the conduit to come up through the pedestal plate,
and there are 1/2" pipe threads in the cast top under the cap
If I am not mistaken Bowser invented the water separator.
I seem to remember seeing a patent for it in my searches.
I made you a copper copy of the part you are missing and will send it to you if you email me your address.
It will be a little over sized, you will need to make the new one out of stronger material, cutting the hex hole will be tricky.
Thanks
Joe
