Step 2

              Removing the Gauge Face Plate and Internals
  • No parts from the old gauge will be re-used, so there is no need to attempt to preserve the parts. However, be careful not to damage the gauge housing.
  • Pry up a corner of the gauge face plate.
  • Use pliers to pull off the gauge face plate.
  • Be careful when prying off the face plate, as the edges are sharp.
  • Use pliers to remove the internal gauge mechanics.

Step 6

              Installing the New Gauge
  • Thread the new gauge into the floor pump by turning it clockwise in its housing.
  • Thread the gauge until it is snug and the BAR/psi markings are aligned with the pump body.
  • Gauge performance will not be affected by its position, so long as it is snug.
  • Allow at least 30 minutes for the thread locker to set.
  • Test pump to its highest rated pressure and listen for leaks. If you can hear leaks from the gauge, tighten it.
