The FS1000-SV-AVS offers surge protection right down to 5% fuel tank capacity and eliminates the requirement or need for an external surge tank for street & track driven applications - see PERFORMANCE below.


  • 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. The FS1000-SV-AVS also features a stainless steel circlip & weld-on flange (available in aluminium; if you wish to machine your own flange, Aftermarket Industries will provide this upon request to customers who have purchased the FS1000) designed to assist with ease of installation and removal yet provide continuous radical force and secure the surge tank against high rotational speeds.

  • AVS: The FS1000-SV-AVS surge tank features our unique Active Valve System engineered to close & trap fuel under acceleration, cornering and braking. The valves then open, when load is reduced, to allow fuel to rapidly re-fill the surge tank.

  • Venturi Vacuum Pump: The FS1000-SV-AVS surge tank also features an internal Venturi Vacuum Pump. Developed in-house using leading CFD modelling software and techniques (200 data points, 250 man hours and 90 hours of continuous simulation), the FS1000-SV-AVS Venturi Vacuum Pump requires no wiring, draws no current yet is able to generate enough vacuum to pull through, using a fitting located on the lowest point of the surge tank, up to 200 litres per hour of fuel into the surge which will ensure that the fuel pumps are submerged at all times and there is no possibility of fuel starvation or fuel surge.

  • Plug & Play: The FS1000-SV-AVS features a 6 Way, bio-fuel compatible (unleaded, ethanol and C16), Plug & Play electrical connector (2x (female submersible connectors included)​

  • 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 surge tank is manufactured using a composite injection moulded plastic commonly used in Formula One and Aerospace applications. Aftermarket Industries products are designed using only best practice engineering principles and are stress tested to ensure safety across all motorsport applications.​​
