I replaced my Racor filter and fuel filter yesterday. Racor I filled with fuel but then just changed the fuel filter and bled the system per the owners manual. Even though it is a 2006 I think it may have been the first time the plunger had been used as it seamed like the plunger was painted shut. I had a hard time releasing it. Finally I did get it to popped up so that I could "plunge". Once I got a steady stream of fuel I tried to keep the plunger down but no matter how I turned it, it would not remain down. My question is, should the plunger be down? I haven't started the engine yet because I was worried about a fuel coming out of the plunger in the up position
