FWC Ranger 33

Hey all,
I have a Ranger 33(1978, original A4) that is new to me this spring, MMI FRESH WATER COOLED and MMI ELECTRONIC IGNITION. The boat has had a few owners since the system was first installed. I have been having all kinds of issues getting the raw water side to pump, I installed a new impeller, faced the sealing surfaces, install a new oring, just to make sure there were no air leaks. When I pulled the pump I noticed that the system has 3/4 hose on many of the 5/8 barbs. I will address this issue this weekend by replacing all the hoses. My question is, should there be a "foot valve" / "check valve" in the raw water supply hose either before or after the strainer? I did not see any hint of one in the drawings on this website, but I thought I read somewhere that there was supposed to be. Any info you can provide is greatly appreciated!

Brian
