I acquired a pump that turns out to not be what it was advertised so I’m looking to identify a few of the parts and then try to salvage this project. When acquired the pump was mostly disassembled, advertised as a Bowser 575, and all significant parts appeared to be included. After getting it home, I tried a test assembly to see how everything fit, only to discover some parts don’t fit! The doors fit size wise, height and width, but the sight glass opening doesn’t align with the sight glass(too low as seen in photo). I’m sure the doors have not been cut down or modified as that would easily be noticeable. The other thing is these door bottoms don’t have as large a bump-out as the 575 doors I’m seeing, but I see nothing in Jack Sim’s book with doors resembling what I have unless they’re possibly not from a Bowser? The top also doesn’t have a cutout to accept the hose nozzle. Any help identifying what these parts actually are would go a ways in helping me determine what needs to be replaced.
