The W110 chassis uses a fuel tank that starts with a 108 part number, so one from a W108 may work, however, looking up the W108 chassis, it shows they use ones with a 109 part number... they look the same, but it appears that the W110 tanks hold 65 liters, while the W108 tanks hold 82 liters.

It looks like they use the same mounting locations, but I'd make sure that there is enough room in there for it to fit widthwise and that the filler neck is the same. Proceed with caution, and it may work... but I think that at the least it may be a larger capacity tank.
