Fuel Catchtanks

A fuel catch tank, also known as a fuel surge tank, is used to prevent the fuel pump from drawing air during long corners or hard acceleration when the fuel moves away from the pump.

A catch tank functions as a small buffer tank that is always kept full. The engine draws fuel directly from this tank, ensuring a consistent supply even when the main tank cannot. This makes catch tanks especially popular in circuit racing, drifting, rally, and tuned cars. Want to build a reliable fuel system capable of handling high power?
Use a catch tank.

Advantages of a catch tank:

• Reliable fuel supply even during cornering and acceleration
• Protects the fuel pump from running dry
• Available in models with external or integrated pumps
• Easy to combine with AN fittings and hoses
