Fuelab 84822-6 Series In-Line Fuel Filter Micron Stainless Steel with Check Valve - 848 75 Black

The Fuelab 848 Series In-Line Fuel Filter (84822-6) combines a high-flow inline fuel filter with an integrated check valve in a single, compact billet aluminum unit. The integrated check valve maintains fuel pressure in the system after engine and pump shutdown, helping to prevent vapor buildup in the fuel rails during engine cool-down — reducing hot-start issues and improving fuel system consistency.

This model features a 75 micron stainless steel mesh element housed in a standard-length 3-inch filter body. The stainless steel element is cleanable and reusable, making it an excellent choice for performance fuel systems that benefit from reduced maintenance frequency and long service life. The black anodized finish is applied per military specification MIL-A-8625, Type II for lasting durability.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown
• 75 micron stainless steel mesh element — cleanable and reusable
• Standard-length 3-inch filter element for high flow capacity
• Billet aluminum housing with black anodized finish (MIL-A-8625, Type II)
• Compatible with gasoline, diesel, methanol, and ethanol fuels
• Male AN flared fitting end caps for direct connection to fuel system components
• Machined internal radii for minimal pressure drop
• Supports up to 200 GPH flow capacity
• 200 PSIG maximum pressure rating
