Description
Radium Fuel Hanger FPR Block Off Plate - Ford Mustang S197/S550 11+
Application: Radium 2011+ Ford Mustang/Shelby fuel pump hangers (20-1800, 20-1801, 20-1802)
Part Type: Fuel hanger FPR block-off kit
Part Number: 20-0806
The Radium Engineering FPR block-off kit converts the Radium 2011+ Mustang/Shelby fuel pump hanger from a built-in regulator dead-head system to a return-style system. It disables the hanger's built-in fuel pressure regulator so an external regulator can be fitted elsewhere in the fuel system, with the return line running back to the tank through the return port on the hanger top plate.
The kit includes an anodised aluminium plate, FKM O-ring and stainless steel plug.
