Fuelab 84831-4 848 Series In-Line Fuel Filter Standard Length 6 Micron w/Check Valve

The Fuelab 848 Series In-Line Fuel Filter (84831-4) combines a 6-micron fiberglass filter element with an integrated check valve in a single, compact unit. The check valve 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 additional fittings that come with it.

Key Features:

• 6-Micron Fiberglass Element – Fine filtration for high-performance and competition fuel systems
• Integrated Check Valve – Maintains fuel pressure after engine and pump shutdown; protected from contamination by the filter element
• Standard Length / 3-Inch Element – Compact design fits a wide range of fuel system plumbing configurations
• Multi-Fuel Compatible – Suitable for gasoline, diesel, ethanol (E85), and methanol fuel applications
• All-In-One Design – Eliminates extra adapters and fittings required when running a separate check valve

The Fuelab 84831-4 is an ideal solution for builders and tuners looking to simplify their fuel system while maintaining reliable filtration and pressure retention. Its compatibility with alcohol-based fuels makes it well-suited for both street performance and motorsport applications.
