DeatschWerks Check Valve

The DeatschWerks Check Valve (also called a one-way fuel check valve or in-line fuel check valve) lets fuel flow in one direction only. It helps stop fuel drain-back in a performance fuel system. Keeping fuel in the line helps with quicker starts, steadier fuel pressure and better street manners. It is made for use in high-performance fuel systems.

Key Features:

• One-way design that prevents fuel from draining back toward the tank
• Helps with hot-start and restart behavior and keeps line pressure more stable
• High-flow design that adds minimal restriction to the fuel system
• Machined T6061 aluminum construction with an anodized finish
• Fuel-safe construction for use in AN-style plumbing
• Compact design that is easy to fit into a fuel line
• Useful in staged or multi-pump fuel systems
