Aeroflow Performance's NEW Single or Dual compact surge tanks are ideal for fuel systems requiring either a single or dual Aeroflow/Bosch fuel pump. These smart little tanks are designed to have the fuel pump/s submerged in fuel for quieter operation and longer life of the fuel pump/s. Both tanks feature -8ORB fittings for a positive seal allowing many options to plumb the fuel system and designed to work with Aeroflow's famous AF49-1014 high flow fuel pump. The tank can be mounted in the engine bay to reduce the work and cost to route from the rear of a vehicle. The twin pump kit is supplied with a block off so you can choose to run one pump and later-on add the second pump and we have also spaced the pumps so that you can use Aeroflow's popular Y-Block (AF939-08-10) that features a female -10ORB outlet. Both tanks available in either polished or black anodised finish, the black anodised finish is what we ecommend for use with corrosive fuels such as Ethanol and Methanol.
