Phenolic Spacer for B/H Mnt. Combination Pump

The phenolic spacer for B/H mnt. combination pump from SWEET is a precision fuel pump adapter designed for high-performance automotive builds where dual-drive systems demand isolation and reliable power transfer. This component solves a critical integration challenge: when converting or upgrading to a hex drive power steering pump paired with a fuel pump configuration, you need a spacer that maintains proper alignment, spacing, and electrical isolation between the two systems. Mechanics and engine builders rely on this adapter to prevent mechanical interference, reduce vibration transfer, and ensure both pumps operate independently without crosstalk—especially in tight engine bay configurations common in street rods, vintage restorations, and forced induction platforms.

Manufactured from phenolic material, this spacer delivers inherent thermal and electrical insulation properties that protect sensitive fuel system components from heat cycling and stray electrical discharge. The phenolic construction is non-conductive and naturally resistant to fuel, oil, and coolant—critical advantages over aluminum or steel alternatives in environments prone to corrosion or where galvanic isolation is necessary. The compact 3.1 x 0.15 x 5.45 inch form factor and minimal 0.05 lb weight ensure minimal packaging impact while providing the structural rigidity required for pump mounting. The hex drive interface ensures positive engagement with your power steering pump's drive mechanism, eliminating slip or misalignment under load.

This adapter is essential for builders transitioning between single-pump and dual-pump fuel and power steering configurations, particularly in engine swaps, LS conversions, and vintage vehicle modernizations. The spacer accommodates hex drive power steering pumps interfacing with standard fuel pump mounting bosses, providing the offset and isolation necessary for proper clearance and operational integrity. Installation requires basic mechanical knowledge—the phenolic material machines cleanly and fastens securely to both pump flanges. Verify your pump's hex drive diameter and your fuel pump flange bolt pattern before ordering to ensure perfect fitment in your specific platform.
