  • MLD+D – Gold cover, copper vent tubing. Suitable for diesel with up to 5% biodiesel.

Why Choose the MLD+?

  • Precision Leak Detection: Unique metering pin design ensures accurate leak detection across all pipework types.
  • Fast Reaction Time: Piston-style construction with reduced internal volume allows quick response to pressure changes.
  • Durable and Reliable: Burnished piston chamber ensures smooth operation and long service life.
  • Low Discharge Pressure: Opens fully during fueling and stays open with pressures as low as 1 PSI (0.07 bar).
  • Easy Identification: Color-coded covers—blue for gasoline, gold for diesel—simplify installation and service.
  • Wide Compatibility: Works with FE Petro™ submersible turbine pumps (STPs) and most other STPs and leak detector housings.
