I'll ask as I'm sure others have been there, my fresh water pump runs but does not pump water...tank is full. I ran out pretty much a full tank of water through it since I brought the 270 home and now it runs but no water is moving...I don't see any type of a filter or anything, assume there is an in tank one....seals???

Open all the valves to let them run for 60sec+/- and it should purge any air that may be hindering a prime if you had run it dry. Otherwise it's a tired pump diaphragm or drawing air from somewhere else.
You did clean that old water system before you ran it after sitting so long didn't you?? Search how to sanitize a RV/boat water system. Keep that crew healthy. Mike

If I run my water tank empty, I usually have to crack the outlet fitting on the pump to get it to prime.2004 250 FV

I too have no water running on my 250 Fiesta Vee, but where is the pump situated,
thanks
I know the dock water/city water inlet is a separate system from your boat's 12v water system - but - if the dock/city water line was leaking (and mine was a week ago) could it let air into your 12v pump lines causing an air lock?
