Hmmm might have something to do with your location ''Florida'' you are close to the Burmuda triangle afterall.... How many pumps did you test??
We had one pump failure almost immediately on the stand when first testing the Kingtech engines. We then took another pump and let it run at 2.1V for a solid 8 hrs (and noted some substantial fod in the fluid), then put it back on the stand and it had delivery issues.
We then ran a second which showed the same signs after around 10hrs.
I recently tested the latest version using the same method for over 30hrs, pump performed better than when pulled out of the box with very little FOD in the fluid. Seems they have fixed the problems with wear....
This is why we packaged the Kingtech with Flightworks pumps. The new Kingtech valves have proven very reliable as well.

We ran the newer pump for up to 40 hours (near 2 service cycles). We achieved similar result as Todd did, stronger pump at an even lower voltage, then we put them on the stand with K-80 running, tapping on the pump to simulate vibrations - zero fluctuation to the RPM.
