Radium Engineering 20-1801 Drop-In Fuel Hanger for 2011-2024 Ford Mustang

Vehicle Fitment

• 2011-2024 Ford Mustang S197 (All Trims - V6, GT, Boss 302, Shelby GT500)
• 2015-2024 Ford Mustang S550 (All Trims - EcoBoost, GT, Bullitt, Mach 1, Shelby GT350, GT500)

Fitment Notes

• Compatible exclusively with Ti Automotive E5LM brushless fuel pump(s) - pumps sold separately
• Supports 1 or 2 Ti Automotive E5LM brushless pumps
• Two unique low-profile SAE quick connect fittings included for S197 and S550 feed line compatibility
• Integrated adjustable FPR can be bypassed for return-style systems using optional Radium kit 20-0806 (sold separately)
• OEM post-pump filter is eliminated - a downstream low-micron aftermarket filter must be installed to protect injectors
• Safe for E85 and all standard fuel types

Features

• Drop-in replacement for the OEM in-tank fuel pump module - no permanent fuel tank modifications required
• Integrated collector box keeps fuel trapped around pump inlets to prevent fuel starvation under aggressive driving
• Integrated adjustable fuel pressure regulator (dead-head style) with vacuum reference port for 1:1 rising rate boost applications
• Redesigned venturi jet siphon system eliminates OEM return line restriction for high-flow pump compatibility
• Anti-rotation stainless electrical studs with hermetically sealed, fuel-resistant connections replace weak OEM multi-pin connectors
• ETFE-insulated submersible in-tank wiring resists all standard and exotic fuels
• OEM fuel level sender transfers directly to hanger - factory gauge functionality fully retained
• Two bolt-on check valves included to enable pump staging (E5LM pumps lack integrated check valves)

Specifications

• Pump Compatibility: Ti Automotive E5LM brushless pump(s) - 1 or 2
• Feed Outlet Port: 8AN ORB (3/4-16 O-ring)
• Return Port: 6AN ORB (9/16-18 O-ring) - plugged; only required with 20-0806 FPR block-off kit

Product Description

The Radium Engineering 20-1801 is a drop-in fuel pump hanger designed specifically for 2011-2024 Ford Mustang owners running Ti Automotive E5LM brushless fuel pumps. It replaces the OEM in-tank module entirely, supporting one or two E5LM pumps in a purpose-built collector box that eliminates fuel starvation under hard cornering, acceleration, or low fuel conditions. The integrated adjustable fuel pressure regulator operates as a dead-head system just like the factory setup, and includes a vacuum reference port for 1:1 rising rate pressure on forced induction builds. The redesigned venturi siphon eliminates the OEM return line restriction, making it safe to run higher-flowing pumps without fuel pressure anomalies.

Installation is a direct drop-in with no permanent fuel tank modification required. Because the E5LM pump lacks an integrated check valve, two bolt-on check valves are included to enable pump staging when running dual pumps. Note that a downstream low-micron fuel filter must be installed to replace the OEM post-pump filter eliminated by this hanger. For users needing a return-style system with an engine bay regulator, the optional Radium 20-0806 FPR block-off kit (sold separately) converts the hanger to a return-line configuration.
