  • Bulkhead Design 
    • We've eliminated the need for 90 degree external fuel hose adapter fittings and simply incorporated a 90 degree thread profile for the Supply & Return ports directly into the bulkhead​​
  • Active Valve System
    • The Pontiac G8 FS1000-V3 Active Valve System significantly reduces to time required to re-fill the bucket by 83%.​​
  • Venturi Pump
    • The Pontiac G8 FS1000-V3 surge tank also includes a Venturi Pump. The Venturi Pump was developed in-house using leading CFD modelling software and techniques (200 data points and 90 hours of continuous simulations) and the result is a Venturi Pump which is able to generate enough vacuum to pull through up to 240lhr of fuel into the bucket which will ensure that the fuel pumps are submerged at all times so there is no possibility of fuel starvation or fuel surge. Note: The venturi pump does not draw any current or require any electrical input to operate.
  • Quiet Operation
    • ​Specially moulded Viton fuel pump noise dampener inserts significantly reduce fuel pump vibration to ensure you have a peaceful in-cabin experience
  • Single Fuel Pump Port
    • Perfect fuel pressure control (staged fuel pump operation) & fuel pressure stability due to our design protected 2-to-1 internal fuel pump manifold.
  • 100% Ethanol Compatible
    • Zero fuel vapour loss and Zero smell GUARANTEED due to anodising process and materials used
  • Quality & Engineering
    • 90% of the components are precision machined from aerospace grade 6061-T6 billet aluminium & the lightweight fuel bucket is designed using best practice engineering principles and stress tested to ensure safety for all motorsport applications. Due to the complexity and the high degree of engineering involved, the lower section of the surge tank is injection moulded with a proprietary super thick, durable and super strong composite fuel (unleaded, race, ethanol) resistance grade of aerospace plastic used by only the most advanced super car manufacturers.
    • Floater valves designs to trap fuel in the fuel bucket
    • Venturi (pump) tube engineered specifically for the GM models.​​

Plug & Play?

While the drop-in surge tank isn't "Plug & Play" per se, the installation can be completed in a mater of hours and will depend on whether the fuel system is setup as a return or non-return system.

Do I Need to Upgrade The Fuel Lines, Fuel Pressure Regulator or Fuel Rail ?

a) Fuel Lines: 

  • Non-Return System (Recommended for Supercharged Applications) The factory fuel supply line is sufficient to support the flow & output of compatible fuel pumps (Walbro 255, 460 and 520 fuel pumps); please note, an external fuel pressure regulator MUST be installed and a new fuel pressure regulator return fuel line installed between the regulator and the FS1000-V3 fuel pump module (-6AN recommended)
    • ​How to Boost Reference (Regulator) Install a billet vacuum block - (NOT included)(billet vacuum block may also be used to reference the Hobbs Switch)
  • Return System (Recommended for Turbocharged Applications): The factory fuel supply is sufficient to support the flow & output of the compatible fuel pumps HOWEVER the fuel rail MUST be upgraded and a return fuel line installed (-6AN return line recommended).

b) Fuel Rail:

  • Non-Return System: Testing has revealed that the factory fuel lines and fuel rail is more than sufficient to support the fuel volume without excessive pressurisation.
  • Return System: Yes, the factory fuel rail MUST be upgraded.

c) Fuel Pressure Regulator: Yes -The OEM fuel regulator is far too small must be upgraded. See AVAILABLE OPTIONS above- "Fuel Pressure Regulator"

  • Pontiac G8 Notes:
      • Fuel Level Sender: The OEM fuel level sender is NOT compatible - One of the following OEM fuel level senders MUST be purchased (NOT PROVIDED WITH THIS KIT): VE 2010+, Camaro ZL1 or VF fuel NOT included with the Pontiac G8 FS1000-V3 surge tank - GM Part Number # 13592329
      • Venturi Cross-Over Hose: The OEM venturi cross-over hose is NOT compatible - Aftermarket Industries will provide a direct replace FREE of charge
  • Aftermarket tune is necessary to ensure correct AFR's and optimal performance
  • OEM FSCM may trigger errors or read lean at WOT due to higher values than OEM settings - please consult with an experienced tuner or ECU hardware & software manufacture; HP Tuners MPVI2 PLUS recommended (visit for pricing: https://www.hptuners.com/mpvi2plus/)
