  • Most differences are in regards to how the hoses, pipes, and tubing are located and connected. Otherwise, the pump itself had very few changes over the years.
  • Use these guidelines below to identify which type you have, so we can supply parts that mount up exactly to your machine.
  • There are less parts drawings than there are variations of the pump types, so some parts for your models will look very different in the drawings, yet are the same part.
  • We do not attempt to supply parts for models older than green (Generally black)
