  • Make sure the sender is fitted with the fuel flow in the direction of the arrow noting that

      flow direction is one way

  • Connect directly with a 3/8" hose, noting that hose clamps should always be used to secure the connection

  • The display comes pre-wired with an approximately 1.4m sender cable  

  • Extra 1.4m & 3m extension leads are available for the three pin plugs

  • Up to 6 leads may be joined to make 9.8m in total length

Connection to 12Volt DC Adapter

 

  • It is recommended that you get the 12v power from the pump circuit

  • Simply cut off the two pin 12v plug to the required length and connect the black wire to the negative terminal and the red wire to the positive power source

  • The back-light will stay ON when connected to 12v

  • All settings and amounts will be stored if power is disconnected
     

 

Current use at 12Volt DC Adapter
