I recently bought and resold a Bowser with those kind of hinges and they look tough to get aligned correct! One of the doors closed nicely and the other was off to one side a little? I was just going to compare side to side and adjust however I could but I sold the pump. I would think that installing a different hinge would require a lot of work. The hinges that come with them, worked at one time, so they should be able to work again.
Good luck!
