Fuelab 84822-4 Series In-Line Fuel Filter Micron Stainless Steel with Check Valve - 848 75

The Fuelab 84822-4 is a standard-length, in-line fuel filter from the 848 Series, featuring a 75-micron stainless steel filter element and an integrated check valve — delivering two critical fuel system functions in a single, compact unit.

The built-in check valve maintains fuel system pressure after engine and pump shutdown, helping to prevent hard starts and fuel pressure drop-off during heat soak. Because the check valve is housed inside the filter body, it is protected from contamination by the filter element itself — eliminating the need for a separate external check valve, additional fittings, or adapters.

Key Features:

• 75-Micron Stainless Steel Element — durable, cleanable, and reusable filtration media
• Integrated Check Valve — maintains fuel pressure after shutdown without a separate component
• Standard Length / 3-Inch Element Size — compact form factor for easy installation
• Multi-Fuel Compatible — suitable for gasoline, diesel, ethanol (E85), and methanol fuel systems
• All-in-One Design — simplifies plumbing by combining filter and check valve in one housing

The Fuelab 84822-4 is an ideal choice for high-performance and alternative-fuel applications where fuel system integrity and pressure retention are essential. The stainless steel element can be removed and cleaned for long service life, making it a cost-effective solution for demanding fuel system builds.
