Here's another thought. You could contact Dieselmeken in Sweden - he did my pump. If he doesn't have access to the right injector (send him the "115" marking info) I'll bet he can tell you who does.

Warning - he speaks and writes Swedlish but really his English skills are pretty good. Be prepared that he may not get your question the first time. I think he augments correspondence from English-speaking customers by running it thru a translator and those are sometimes off a peg or two.
