Buying Guide

What should you check when choosing a 100 micron inline fuel filter at 3/8 inch?

  • Filter type and micron rating: 100 microns captures finer particulates while balancing flow. Ensure the rating matches your engine’s fuel cleanliness needs.
  • Connection size and adapters: A 3/8″ barb inlet/outlet is common, but confirm compatibility with your fuel hose inner diameter and available adapters (6AN/8AN/10AN or 1/2″ fittings).
  • Material and finish: Aluminum bodies are lightweight and corrosion-resistant; stainless steel elements resist rust but may be heavier or pricier.
  • Mounting options: Brackets and mounting hardware help secure the filter in tight spaces and reduce vibration. Check clearance with other components.
  • Replaceability and maintenance: Some models offer easy disassembly for cleaning or element replacement. Consider how simple maintenance is in your setup.
  • Compatibility with fuels: Confirm whether the filter is rated for gasoline, diesel, ethanol blends, or E85, as some have limitations.
  • Integrated vs. replaceable elements: Some kits include the complete assembly; others provide only the filter element. Determine what you need for ongoing service.
