Radium Fuel Hanger FPR Block Off Plate - Ford Mustang S197/S550 11+

Radium Fuel Hanger FPR Block Off Plate — Ford Mustang S197 / S550 (2011+)

This kit bypasses the integrated fuel pressure regulator on Radium fuel hangers (20-0800, 20-0801, 20-0802), allowing an external aftermarket fuel pressure regulator to be used in its place. An essential upgrade for high-power Mustang builds running a standalone FPR for precise fuel pressure control.

Kit includes a Viton O-ring, anodized aluminium block-off plate, and stainless steel plug for a clean, leak-free installation.

Suits:

• Ford Mustang S197 (2011+) — with Radium fuel hangers 20-0800, 20-0801, or 20-0802
• Ford Mustang S550 (2011+) — with Radium fuel hangers 20-0800, 20-0801, or 20-0802

Important Notes:

1. A 6AN ORB fitting is required for the return port. If the rear seat is being retained, a low-profile 6AN ORB fitting must be used to maintain clearance.
2. A fuel pressure regulator (not included) must be installed downstream in the fuel system. Installation of the external FPR is not covered in the included instructions.
