TOYOTA LANDCRUISER 79 SERIES 2.8L DUAL CAB

105 LITRE AUXILIARY LONG RANGE FUEL TANKS

Brown Davis is proud to release a mid-chassis long range auxiliary fuel tank for the latest Toyota Landcruiser 79 Series 2.8L Dual Cab. Due to the new 4 cylinder auto powertrain in the current 79 Series Landcruisers, a completely new design was required for an auxiliary tank.

The Brown Davis 105L Auxiliary Fuel Tank takes the Toyota Landcruiser 79 Dual Cab from a decent 130L fuel capacity to a massive 235L. Say goodbye to range anxiety and hello to the most remote of adventures with a predicted increased fuel range of 2448 kms! Furthermore, the Brown Davis auxiliary tank is located in the middle of the vehicle, ideal for weight distribution.

The Landcruiser 79 Dual Cab Auxiliary Tank fits with most aftermarket single exhausts. Twin Exhausts however may require alteration. The base of the Brown Davis tank follows the line of the vehicles chassis, having no effect on the vehicles ground clearance or ramp over.

INDEPENDENT FEED SYSTEM (MOST POPULAR)

PART NUMBER: TL79DCA5

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
