Fuelab 84812-5 Series In-Line Fuel Filter Micron with Check Valve - 848 40

The Fuelab 84812-5 is a standard-length 848 Series In-Line Fuel Filter featuring a 40-micron stainless steel filter element and an integrated check valve — delivering two critical fuel system functions in a single, compact unit.

The integrated check valve allows your fuel system to maintain fuel pressure after engine and pump shut down, eliminating the need for a separate check valve component and the extra fittings required to adapt it into your fuel line. Because the check valve is housed inside the filter body, it is protected by the element itself, extending the life of the valve and simplifying your installation.

Key Features:

• 40-Micron Stainless Steel Element — durable, cleanable filtration media for long service life
• Integrated Check Valve — maintains fuel pressure after shutdown without a separate component
• Standard Length / 3-Inch Element Size — compact design for easy inline installation
• Multi-Fuel Compatible — suitable for gasoline, diesel, ethanol (E85), and methanol fuel systems
• Eliminates additional fittings and adapters required by standalone check valve installations

The Fuelab 848 Series is engineered for performance and forced-induction fuel systems where holding fuel pressure between start cycles is critical. The stainless steel element is designed for repeated cleaning and reuse, reducing long-term maintenance costs compared to disposable paper-element filters.
