[QUOTE="Garbage_Mechanic, post: 836681, member: 1610"] Continuing on that thought, the proper way to test a pump with it NOT connected to the system is serves, because if there are any variances in the system it will affect the outcome. In the hydraulic world, a controlled temp standardized oil would be used. The RPM would be controlled, inlet vacuum would be controlled and the the GPM and pressure recorded at various engine rpm. Now we really will know what pump does what. [/QUOTE]
