Surge Tanks

A surge tank is a critical component for high-performance and track-driven vehicles, preventing fuel starvation during aggressive cornering, acceleration, or braking. When the fuel sloshes away from the pickup in the main tank, the surge tank acts as a small reservoir that maintains a steady supply to the engine, ensuring consistent fuel pressure and preventing dangerous lean conditions. This collection brings together a range of surge tanks suitable for EFI and carbureted systems, from compact 1-liter units to larger capacities for high-horsepower applications.

Key considerations when choosing a surge tank:

  • Capacity: Match the tank volume to your engine's fuel demand. Smaller tanks (0.5-1.5L) work for most street/strip cars, while dedicated race cars may require 2L or more.
  • Material: Billet or fabricated aluminum is common for durability and heat dissipation. Some tanks feature black anodized finishes for corrosion resistance.
  • Fittings and Ports: AN (usually -6 or -8) threaded ports allow secure, leak-free connections. Look for multiple feed and return ports to accommodate various plumbing layouts.
  • Pump Integration: Some surge tanks include an integral mounting flange for an in-tank fuel pump, simplifying installation by eliminating the need for an external pump.
  • Brackets and Mounting: Many tanks come with universal mounting brackets or provisions for custom mounting. Ensure the location is secure and away from heat sources.

Whether you're building a time attack car or upgrading your weekend track toy, a properly sized surge tank is cheap insurance for your engine. Browse our selection to find the right tank and keep your fuel system reliable under all conditions.
