Many parts are replaceable on the pump, me, I am too lazy, and have a lack of tools, so I opted just to fork out the $100 for a new one. If I had had the time I would have shopped around and probably gotten it cheaper, but we were on the road and since we dry camp 99% of the time not having a pump was not optional.
Besides removing & replacing 4 screws and two hose connections was easier than tearing the pump apart to fix the problems it was having--leaking, not shutting off and finally not running at all--and hoping it would work after the time and money invested.
