Fuelab 84801-4 Series In-Line Fuel Filter Standard Length Micron with Check Valve - 848 10

The Fuelab 84801-4 is a standard-length, in-line fuel filter from the 848 Series, featuring an integrated check valve and a 10-micron replaceable fabric element. This combination allows your fuel system to maintain residual fuel pressure after the engine and pump shut down — eliminating the need for a separate check valve component and the extra fittings that come with it.

Key Features:

• 10-Micron Replaceable Fabric Element — traps fine fuel contaminants to protect downstream fuel system components
• Integrated Check Valve — maintains fuel pressure after shutdown; protected inside the filter housing for added durability
• Standard Length Housing with 3-inch element size
• Broad Fuel Compatibility — compatible with gasoline, diesel, ethanol, and methanol fuel blends
• All-in-one design eliminates the need for separate check valve adapters or additional fittings
• Replaceable element design for easy, cost-effective maintenance

The Fuelab 848 Series in-line fuel filter is engineered for high-performance fuel systems that demand clean, consistent fuel delivery. The integrated check valve shields it from contamination while keeping your fuel rail primed and ready, reducing hard-start conditions and protecting fuel injectors.
