I am looking for someone that has a 80 with a 1hdft near Richmond Virginia. I have developed an aneroid pin that fits my 12mm 1hdt injection pump but I have not tried it in a 1hdft and would like to. I'm selling these aneroid pins and want to ensure it fits the 1hdft 12mm injection pump. Everything I've read, the pin should fit fine. Appreciate the help.
