Radium Fuel Hanger FPR Block Off | Universal (20-0806)

The Mustang hanger's built-in regulator steps aside, and the return system steps in.

The Radium Engineering Fuel Hanger FPR Block-Off converts the Radium 2011+ Mustang fuel pump hanger from its built-in-regulator dead head configuration to a return-style system: the block-off replaces the integrated FPR, regulation moves to an external regulator at the engine, and the hanger's 6AN ORB return port comes into service carrying fuel home.

What You'll Feel

• Full return-style architecture on the Radium Mustang hanger platform
• External regulator placement at the engine, referenced where pressure matters
• The hanger's preinstalled return port plug finally earning its replacement

Features

• FPR block-off for the Radium 2011+ Mustang fuel pump hanger (20-0800 family)
• Converts the integrated-regulator dead head system to return-style
• Activates the hanger's 6AN ORB return port for return line connection

The Details

The hanger's integrated FPR serves most builds cleanly, regulating at the tank at a 1:1 rate, but some tuning strategies want the regulator at the engine, closer to the rails with its vacuum reference reading manifold directly, and the block-off is the conversion path: FPR out, block-off in, external regulator plumbed, and the return line landing on the hanger's 6AN ORB port through Radium's adapter fittings (sold separately). Standard ORB discipline at every step, O-rings lubricated, no sealant, and the Mustang's fuel architecture reshapes without touching the tank again.
