Fuelab 84811-4 Series In-Line Fuel Filter Micron Stainless Steel with Check Valve - 848 40

The Fuelab 84811-4 is a 848 Series Standard Length In-Line Fuel Filter featuring a 40 micron stainless steel filter element and an integrated check valve — combining two critical fuel system components into a single, compact unit.

The built-in 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, additional fittings, or adapters. Because the check valve is housed inside the filter body, it is protected by the filter element itself, helping to extend check valve service life.

Key Features:

• 40 Micron Stainless Steel Element — durable, cleanable filtration for long service life
• Integrated Check Valve — maintains fuel pressure after shutdown; no separate component required
• Standard Length / 3-Inch Element Size — fits a wide range of inline fuel system configurations
• Multi-Fuel Compatible — compatible with gasoline, diesel, ethanol (E85), and methanol fuels
• Simplified Installation — eliminates extra fittings and adapters associated with separate check valve installation

The Fuelab 848 Series is an excellent choice for performance, racing, and alternative-fuel applications where maintaining fuel system pressure and cleanliness is critical.
