FUEL SYSTEM OPTIONS

OPTION 1: INDEPENDENT FEED SYSTEM (DIESEL ONLY) (MOST POPULAR)

PART NUMBER: TL79A4

This system is designed as a change over system, which means at the flick of a switch the driver can independently feed the engine directly from either the main or Brown Davis auxiliary tank.  This allows you to manage weight distribution by draining the rear tank first to keep weight forward of the rear axle. This is the same system as the early 79 Series single cabs and 100 series with twin tanks.  All parts and hardware for install are supplied. 

LED Auxiliary Gauge

Led gauge supplied in the independent feed system to monitor the fuel level in the auxiliary tank. Installed typically under the dash above the gear stick in a 79 series

MAIN/AUX Rocker Switch

Allows you to quickly choose which tank you wish to feed the engine from. Installed in a factory Toyota switch knockout. 

6 Port Change Over Valve 

Function: 

  • Feed from main tank
  • Return to main tank
  • Feed from auxiliary tank
  • Return to auxiliary tank
  • Feed engine
  • Return from engine

OPTION 2: TRANSFER SYSTEM (PETROL AND DIESEL)

PART NUMBER: TL79A2

This system is designed to pump the fuel from the Brown Davis auxiliary fuel tank into the vehicles standard fuel tank. At the flick of a switch fuel will be pumped into your vehicles standard tank to then be feed to the engine. An LED gauge is supplied to show driver the fuel level of the auxiliary fuel tank at all times. When the auxiliary tank becomes empty an automatic alarm will sound to tell driver to switch pump system off. This prevents pump from continuously running which can course pump failure. All parts and hardware for install are supplied

Fuel pumps burning out is now a thing of the past. Brown Davis has developed a new auxiliary fuel tank gauge, switch and buzzer unit to be supplied with most Brown Davis auxiliary transfer fuel tanks. the small unit is no bigger then a 10 cent coin and can be mounted nicely in vehicles dashes.

TANK FULL – FUEL NOT TRANSFERRING

THE LED GAUGE WILL SHOW TANK LEVEL AT ALL TIMES EVEN IF PUMP IS NOT RUNNING.

TANK FULL – FUEL TRANSFERRING

WHEN BUTTON IS PRESSED THE PUMP WILL BEGIN TRANSFERRING FUEL ACROSS TO YOUR VEHICLES MAIN TANK. THE ROUND YELLOW LED LIGHT SHOWS PUMP IS RUNNING

TANK HALF FULL – FUEL TRANSFERRING

AS FUEL IS BEING TRANSFERRED ACROSS THE LED LIGHTS WILL SHOW FUEL LEVEL REMAINING IN YOUR AUXILIARY TANK. AT ANY STAGE YOU CAN PRESS THE BUTTON AND STOP THE TRANSFER OF FUEL.

TANK EMPTY – FUEL TRANSFERRING

WHEN TANK IS COMPLETELY EMPTY A BUZZER WILL SOUND AS A REMINDED TO TURN THE PUMP OFF. LEAVING FUEL PUMPS ON FOR LONG PERIODS OF TIME CAN BURN THEM OUT
