For reasons I won't bother to explain here (Chumpcar), I need a really cheap water injection system. I made one for Bonneville using an old fuel injection pump, and it failed right at the end of the event. Now, it was old and crappy in the first place, so it might have failed no matter what. My question is, has anyone used a standard injection pump for water for any length of time? Mine needs to run 24 hours.
