The Holley 134-331 1850-15 600 CFM Vacuum Secondary Fuel Body is a high-performance fuel system component designed for serious automotive enthusiasts and race applications. This secondary fuel body is part of Holley's renowned line of Sprint-Jet fuel systems, which have long been a favorite among hot rodders, drag racers, and other power enthusiasts.

This particular fuel body carries a flow rate of 600 CFM (cubic feet per minute), making it suitable for larger engines that require more fuel to maintain optimal performance. The body is constructed of high-quality aluminum, which not only ensures durability but also helps to keep the weight down, contributing to better engine response and overall vehicle performance.

One of the most distinctive features of this fuel body is its vacuum secondary design.

The secondary diaphragm is designed to maintain a constant fuel pressure, even under varying engine RPMs and load conditions.

Another important aspect of this fuel body is its compatibility with various Holley fuel systems. It can be used as a standalone component or integrated into a complete Holley fuel system, such as the Holley Terminator X or Holley Sniper EFI systems. This versatility makes it an excellent choice for a wide range of applications, from street rods and muscle cars to high-performance racecars.
