The Flojet push lock fitting started leaking again today. It looks like the brass insert in the fitting it coming out. I just replaced it with about 5 other fittings (last picture).
What happened was the tire cleaner leaked on top of the holding tank. Then the chemical leaked through the holding tank hinges. This made the foam bush, high pressure soap and rinse water all be tire cleaner. I had to siphon out all the tire cleaner.
