   * **A hole in a piston would probably tell on itself** as in the pics below. \\ A dual psi gauge was set up at 92 psi, then the outlet was opened up, full hose, with the readings recorded in the second pic. \\ This left an inlet side 60 psi and outlet side of 48 psi while flowing from a small peanut air tank. It was more of a high pressure sound than a hiss.   * **A hole in a piston would probably tell on itself** as in the pics below. \\ A dual psi gauge was set up at 92 psi, then the outlet was opened up, full hose, with the readings recorded in the second pic. \\ This left an inlet side 60 psi and outlet side of 48 psi while flowing from a small peanut air tank.
