I dismantled a unit from a junkyard a few years ago. It was an 86 300e with about 275k. There is only one piece of rubber gasket and some o-rings. Everything looked to be in perfect condition.

My 300e fuel dizzy has never been rebuilt, cleaned or even adjusted. It still works perfectly.

There are too many other maintanence items on the m103 to bother with (in my opinion) a bullet proof fuel distributer.
