Description
 
  • Aerospace grade trigger switch for secondary pumps
  • Gold plated internal contacts and Kapton diaphragm ensure reliable long term service
  • Preset for 4 psi actuation (ON/CLOSED above 4-5 psi)
  • 1/8 NPT male interface is compatible with our push on boost/vacuum hose and fittings
  • Optional sealed Aptiv (Delphi) Metri-Pack 280 connector and 15 feet of 18 gauge bonded wire
  • Optionally available black anodized barb fittings for 1/4" [6mm] or 3/16" [5mm] inside diameter hose

INSTALLATION AND USE
  • For professional installation only
  • Must be used in conjunction with a relay or load handling device (such as FC3)
  • Mount to avoid engine vibration. Do not mount directly on engine, intake/tubing, supercharger, etc.
  • Only primary pump will run during prime and engine start. Ensure fuel line is checked so it is full of liquid fuel for quick pressurization.
  • Ensure primary pump is adequate to supply motor beyond 5 psi boost, otherwise the engine may starve for fuel before secondary pump(s) are activated.
  • Consider the Honeywell Vacuum Switch if the engine requires the secondary pumps to be activated earlier
