There was a cracked fitting between the pump head and the unloader. I decided to replace the fitting. Then I decided to replace the hose that runs from the pump to the high pressure hose. I assumed that it was the size of a swivel saver. Which it was not. I cut the hose with a grinder because it had no swivels on it. Then I had to put a boom hose in its place but no water would come out at the bay. The pump got super hot and I have no clue what the problem is. So I gave up. I will need to look at it tomorrow.
