This component is a modification or addition to a fuel reservoir designed to ensure a consistent fuel supply to the engine, particularly during periods of high acceleration, deceleration, or cornering. It typically involves a small reservoir built within or attached to the main fuel tank. This reservoir maintains a reserve of fuel immediately available to the fuel pump pickup. For example, a fabricated steel enclosure welded inside a gas tank can act as this reserve, capturing fuel and preventing fuel starvation.
The incorporation of this feature addresses a common issue in vehicles experiencing rapid changes in direction or speed. Without it, the fuel in the tank can slosh away from the fuel pump pickup, resulting in a temporary loss of fuel pressure and potential engine misfires or stalling. Its implementation is particularly beneficial in high-performance vehicles used in racing or spirited driving, where consistent fuel delivery is critical for optimal engine performance and reliability. Historically, these solutions were often custom-fabricated, reflecting the needs of specific vehicle applications and performance requirements.
