Hey, I'm new at this, so please bear with me. I have had a 1975 SRV 220 Cuddycabin for about 11 years. Still runs great and am always getting compliments on it. I have been unable to locate the filler neck and the sending unit on the 70 gal. v-bottom belly fuel tank on this boat. Does anyone out there have a clue where these are? I don't really want to tear up my deck!
