Fuel/Water Separator, National Tropical T33 w/Cummins 300

Bump. This info is for my neighbors who are heading out in their motor home tomorrow. If you don't know where the fuel/water separator is, do you know where we might inquire on the net or otherwise?

Thank you for reading and any help will be greatly appreciated. I could always call my neighbors with the info while they are on the road.
