Fuelab 858 Series Fuel Filter with Check Valve -8AN 100 Micron Stainless in Gold (flb85821-5). Fuelab's 858 Series takes the long 5 inch filter body and adds an integrated check valve downstream of the element, where the element protects the valve from debris. Configured with a 100 micron stainless steel element and -8AN ports.

The 100 micron stainless steel element is intended for use as a pre-filter ahead of a fuel pump, where it helps prevent pump cavitation with very low pressure drop. Fuelab recommends a finer element downstream to protect injectors or carburetors.

Key Features

  • Integrated check valve assembly on the outlet side of the filter
  • Helps maintain fuel pressure after engine and pump shut down
  • Aerospace inspired poppet with a fluorosilicone soft seat
  • Rated up to 2000 HP
  • 5 inch element for greater flow and increased filtration capacity
  • -8AN male 37 degree flared inlet and outlet caps
  • Gasoline, diesel, methanol and ethanol compatible
  • Billet aluminum body anodized per military spec MIL-A-8625, Type II
  • Machined internal radii for minimal pressure drop
  • Replaceable or cleanable filter element
  • 200 PSIG maximum pressure rating

Fitment

Universal application. This is a universal in-line fuel filter and is not specific to a vehicle year, make or model. Select by inlet and outlet AN size to match your existing fuel system plumbing, and by element micron rating for the position it will run in.
