Product Details

The DeatschWerks 6-02-0450-B is a precision-engineered 4AN ORB (O-Ring Boss) male to female check valve designed specifically for use with DW810 fuel pump systems. This one-way valve prevents fuel from flowing backward in the system, maintaining proper fuel pressure and eliminating hot start issues commonly experienced with aftermarket high-performance fuel pumps.

Key Features:

  • Precision-machined from T6061 aluminum for strength and durability
  • Matte black anodized finish for corrosion resistance
  • 4AN ORB male to female configuration for direct integration
  • One-way design maintains fuel system pressure
  • Prevents fuel drain-back and improves pump priming
  • Compatible with ethanol-blend fuels and racing fuels
  • Engineered for high-performance fuel system applications

DeatschWerks check valves are essential components for maintaining consistent fuel pressure in modified fuel systems. By preventing fuel from draining back through the system when the engine is off, this check valve ensures quicker starts and more reliable performance, particularly in hot-start conditions where fuel vaporization can be problematic.

Great pricing fast shipping, flawless transaction!

Ordered 8 11R24.5 tires... Price was good and they shipped out in a day or two. Did not receive in 2 days as promised but that was Fed X's fault not THMotorsports. Would buy from again...
