I've got a 1979 37 cutter with a dirty fuel tank (40 gal.) and am looking for some info: 1- Does the fuel pick-up have a screen on it? If so, how do I get at it to clean/remove it? (The shut off valve for the pick-up is threaded into the side of the tank.) 2- Is the tank baffled? If so, where are the baffles? (In the event I cut access holes to clean the tank.) 3- Has anyone else had this problem with this boat/tank? If so, did you cure it, and how? Any and all help is appreciated! Thanks, Scott
