Howdy Campbell, welcome to the tractor forum.

Minimec injection pumps are not very well known. We have an injection pump specialist that frequents this forum, but last I heard from him, he was swamped with work. He hasn't visited the forum much lately.

Hello campbell graddy. Sorry that you haven't had a response. Perhaps my reply will bump up this post.
We have a few good pump guys here that I am sure will pop in before too long.
In the mean time, there is a site in the UK that has parts for these pumps. I just did a quick search, is all.

Thanks for responding..
