W126 fuel tanks, all the same?
 

The fuel tank on my SD has a leak near the filler neck and it's not fun driving about smelling like diesel fuel. It's hard for me to come upon S-class diesel tanks but I can get S-class gas tanks easily.

Be that as it may, if I had the gas tank washed out internally could I use it in place of my existing diesel tank or do I need to flat out find a diesel tank?

Thanks for any help! :)

S-class gas fuel tank will not fit your 300 SD but is will fit your 300SDL they are the same part number.

Hrm, odd as the wheel base is longer on the SDL over the SD.

Any clue as to which tanks fit the SD?

126 470 16 01 fuel tank only fit 300SD 126.120 USA

Much appreciated. :)

The shape may be the same, but the diesel tanks have fittings for the return line. I bet thats why the part numbers are different. If you can get a tank out of a gas car cheap enough I would compare them and see if you can safely make it work.

Would a tank from a W116 work? I found a solid one here yesterday
