These Aeroflow Performance Under-Car Surge Tanks are designed to prevent starving the fuel pump by increasing the fueling capability of the fuel system. It is usually installed in vehicles that potentially can experience fuel starvation due to fuel sloshing around in an inadequately baffled fuel tank/cell. While this can occur in any vehicle when the tank is not fully filled, it is more frequent in vehicles subject to violent changes in directions such as autocross, off-road, drag racing and other types of racing that involve high g-force. The primary fuel pump in the vehicle's main fuel tank will no longer directly feed the engine. Instead, the internal fuel pump will now be used to fill and maintain the level of fuel in the surge tank itself. Using a surge tank will now require new external fuel pump/s to be installed after the tank to supply fuel to the engine.

This surge tank is specifically designed to be mounted under the vehicle in a horizontal position. It should not be installed inside the vehicle or in a vertical position.

The tank itself is robotically TIG welded with 2.5mm thick aluminium, featuring six female -8 O-ring ports that allow vast variety of adapter fittings to be placed into various positions around the tank if required. NOTE: if not using all ports ensure to block them with fittings (sold separately). The kit includes a billet dual fuel pump holder along with our -8ORB to -8AN adapters designed for external60mm diameter fuel pumps such as our AF49-1014 or Bosch Motorsport 044 which are Sold Separately.

Each tank is available in polished or black finishes.
