What is Up with My Hardi Sprayer

I bought this Hardi sprayer in the summer of 22 and started rebuilding. I had to start with a complete redesign because I could not get parts from Hardy. My local dealer is an hour away and they were not very friendly in giving any help. So, I ended up going to FDS, Fertilizer Dealer Supply. They are about 25 minutes from me. They carry all of the popular brands and parts that would repair fertilizer equipment. It was going to be a winter project but that didn't happen. After months of working on what parts I had available, I now have it just about competed.
