Radium Engineering 20-0762 Fuel Line Retaining Kit for 2020+ Toyota MK5 GR Supra

Vehicle Fitment

• 2020+ Toyota GR Supra (A90/A91; B58TU; All Trims)

Fitment Notes

• The 20-0762 replaces the OEM plastic fuel line retaining clips on the undercarriage of the MK5 GR Supra with billet aluminum retainers that accommodate the larger-diameter aftermarket AN fuel lines used in port injection and high-flow fuel system builds. All retainers mount to the same OEM thread locations as the factory clips - no drilling, cutting, or permanent modification to the chassis is required.
• This kit is designed for use with the Radium 20-0761-0X Fuel Hanger Plumbing Kit, which routes 8AN feed and 6AN return hoses from the Radium 20-0760 fuel pump hanger along the GR Supra's undercarriage to the engine bay. The retainer slot dimensions are sized for the Radium plumbing kit's specific hose outer diameters. Compatibility with other brands' fuel hoses of different outer diameters - including rubber, braided, PTFE, aluminum, or steel lines - cannot be confirmed by Radium Engineering.
• The 20-0762 retainer kit is also included as a component in the 20-0761-0X Fuel Hanger Plumbing Kit. This standalone listing is for customers installing the retainers separately or replacing a retainer set purchased as part of a prior plumbing kit purchase.
• Aftermarket fuel lines are not included with this kit. The retainers are brackets only - fuel hose and fittings must be sourced separately.

Features

• Billet 6061 aluminum construction replacing OEM plastic clips - the factory GR Supra uses plastic retaining clips to secure the OEM fuel feed and EVAP lines along the undercarriage; these clips are sized for the OEM line diameters and do not have additional slots for the larger-diameter aftermarket AN hoses required by a port injection fuel system; the Radium billet aluminum retainers replace each OEM clip location with a unit that provides both the OEM line slots and additional slots for aftermarket fuel lines running the same undercarriage path
• Multiple retainer configurations for full undercarriage coverage - the kit includes retainers sized and configured for each unique location along the fuel line path from the rear of the vehicle to the front; a 4-way retainer toward the rear of the vehicle accommodates the higher line count where feed, return, and EVAP lines converge; a 2-way retainer at the rearmost position is specifically shaped to prevent the crossing fuel lines from making contact with the driveshaft and exhaust when the lines transition over the transmission tunnel - a safety-critical function that the OEM plastic clip at this location does not provide for aftermarket line sizes
• Uses all factory mounting locations - each retainer in the kit mounts directly to the existing OEM threaded fastener locations on the GR Supra chassis; no new holes are drilled, no brackets are welded, and no existing hardware is permanently removed; the installation is fully reversible
• Anodized 6061 aluminum with stainless steel hardware - anodizing protects the aluminum retainer bodies from corrosion in the undercarriage environment, where exposure to road salt, moisture, heat from the exhaust, and fuel splash is constant; stainless steel fasteners prevent corrosion seizure at the OEM mounting threads over the life of the installation
• Prevents fuel line contact with driveshaft and exhaust - at the tunnel crossover location, the rearmost 2-way retainer is specifically engineered to hold the aftermarket fuel lines clear of the rotating driveshaft and hot exhaust components; without a correctly positioned retainer at this location, larger-diameter aftermarket fuel hoses can contact these components, leading to chafe, heat damage, or catastrophic hose failure

Product Description

The Radium Engineering 20-0762 is a fuel line retaining kit for the 2020+ Toyota GR Supra (A90/A91) that replaces the OEM plastic undercarriage fuel line clips with billet anodized 6061 aluminum retainers sized to accommodate both the OEM lines and the larger-diameter aftermarket AN fuel hoses used in port injection and high-flow fuel system builds. The GR Supra's factory plastic clips secure the OEM fuel feed and EVAP lines along the undercarriage from the rear of the vehicle to the front engine bay, but these clips are sized only for the OEM line diameters. When the Radium port injection fuel system is installed - using the 20-0760 fuel pump hanger and 20-0761-0X plumbing kit - 8AN feed and 6AN return hoses must run the same undercarriage path and require retainers with additional, appropriately sized slots.

The kit provides multiple retainer configurations that address each location along the fuel line path. The rearmost retainer is a 2-way design specifically shaped to hold the fuel lines clear of the driveshaft and exhaust system where the lines cross over the transmission tunnel - a location where unsecured or improperly retained aftermarket hoses can chafe against the rotating driveshaft or contact hot exhaust surfaces. All retainers mount to the existing OEM threaded fastener locations with no drilling, cutting, or permanent chassis modification. Stainless steel hardware prevents fastener corrosion at the OEM mounting threads in the undercarriage environment.

The 20-0762 retainer kit is also included as part of the Radium 20-0761-0X Fuel Hanger Plumbing Kit; this standalone listing serves customers sourcing the retainers separately. Aftermarket fuel lines are not included. The retainer slot dimensions are designed for the Radium plumbing kit hose sizes; compatibility with other brands' fuel hoses of different outer diameters cannot be guaranteed.
