has anyone actually used one of these pumps?
I have heard of most pumps but not heard of this one, and the size of motor & pump head looks the same as Shurflo & Flojet but they don't make a pump that size that will go to 170psi.
which makes me wonder how this company can without over running the motor which would make them a bit suspect.
but I might be totally wrong, just enquire about the guarantee before buying
