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.
