Billet Fuel Filter Mounting Brackets — Holley 162-573 & 162-574 (Black)

Secure, clean mounting for inline fuel filters. Choose the clamp that matches your filter’s outside diameter (OD): 1.50" OD → 162-573, 2.00" (50.3 mm) OD → 162-574. Black-anodized billet aluminum with a rigid, low-profile design and multiple mounting options.

Why builders choose these brackets

  • Exact OD fit: 1.50" or 2.00" (50.3 mm) clamp bores for rattle-free, secure mounting.
  • Rigid & reliable: 1/2" thick billet body resists vibration and flex.
  • Flexible mounting: through-bolt pattern plus threaded base (see specs) to suit frames, rails, or tabs.
  • Plays nice with your system: Fits popular Holley, Earl’s, and Aeromotive filters with matching OD.
Quick fit check: Measure your filter body OD with calipers.
If it’s ≈ 1.50" (38.1 mm), select 162-573. If it’s ≈ 2.00" (50.3 mm), select 162-574.

Install notes

  • Mount to a flat, rigid surface; support long filter/hose runs every 12–18".
  • Use 1/4" hardware for through-bolts. For 162-574’s threaded base, use M6 × 1.0 fasteners.
  • Orient the clamp so service screws are accessible; do not crush the filter body—snug evenly.

What’s included

  • (1) Black-anodized billet clamp (choose 162-573 or 162-574).
  • Clamp hardware for the two-piece ring. Chassis mounting bolts are not included.
