      Certainly a possibility. A quick calculation shows that the oil pressure against the piston o-ring is 77psi @ 1725 rpm. That's easily...

      The thinking was twofold: As the piston went to bottom dead center, the oil on the back end of piston would get pushed out of the...

      I got all the pa;rts finished, bolted the pump to the motor and ran some tests. The results are pathetic. The pump only generates...
