2001 Cummins ISB oil pressure sending unit

#1
I want to install a bypass oil filter on my Cummins ISB that is in my motorhome.

From underneath, I don't see the oil sending unit anywhere. Is this one of those things where I am going to have open up from the top (underneath the bed). I never opened it up from above before...

Or am I just missing it somehow?

Or is there another / better place to grab the incoming oil?

Thanks,
