I have a Groco HF head in an ODay 272 that has not been operated in some time (2+ yrs). Opening the intake thruhull and gently operating the pump T-handle yields squeaky sounds but no water into the bowl. The valve handle is in the vertical position. I've considered taking the hose, from the top of the pump to the back of the bowl, loose at the bowl, and try to prime the pump. The squeaks indicate to me that seals, etc. haven't seen water lately. Is this a reasonable attempt at getting the head up and running again or have I engaged in wishful thinking?
