I think accel and mallory also make these but they all tend to be more exoensive than the rotary vane pumps. the gerotor type pumps are extremely rugged compared to the rotary vane type pumps (like holley red, blue, black to name a few). Gerotor type pumps have been used forever in the oil patch industry due to their ruggedness and superior suction qualities. Could you buy me one too Pat?
