i read some of the postings on fuel distributors that were listed, i noticed a few were old so i thought i'd try my luck. i have a 1979 450 sl with fairly low miles. the miles are low because it hasn't run right in a long time. four fuel distributors later, i'm in need of a rebuild kit. all the ones i have gotten from junk yards and on ebay used have one or more fuel outputs not functioning properly whether cast iron or aluminium. these rebuild kits have got to be available...i'm gonna try a boshe supplier this week. has anyone found out where to find a rebuild kit, or a way of making your own new diaphram? any help would be greatly appreciated...
