This is a 1970, 280sl. You can see the new tank and the old tank. On the old tank, you can see a "splice" in the upper right corner, by the guage. I don/t know if that is original or was done by the original owner. I can't see any other clamps, just molded plastic to molded plastic. I can't think of why only that one would be like that. I would like to keep the connections as period/original as possible.
I haven't taken the gas tank off to see how those were done yet. I will research as Kayvan suggested, everything I have researched on this site has been a great help. This is the greatest site ever!!!!!
mdsalemi-I can/t picture where the brass tubes and Bob said he had aluminum tubes with the 1970. Do you guys have pictures?
