Radium Fuel Hanger Plumbing Kit | 2014-2019 Chevrolet Corvette C7 (20-1011-03 / 20-1011-05)

Direct injection means the OEM high pressure pump still runs the show, and it needs a properly regulated low side to do it.

The Radium Engineering fuel hanger plumbing kit for the 2014-2019 Chevrolet Corvette C7 provides all necessary plumbing to and from the engine for the Radium 20-1010 fuel pump hanger: an MPR-RA fuel pressure regulator, a fuel pressure gauge, a check valve fuel filter, C7-specific mounts, PTFE lines, adapter fittings, and hardware. From the hanger's pump outlet, 8AN PTFE hose runs to a chassis-mounted filter near the tank, with an inline tee that preserves the use of the OEM fuel pressure sensor for tuning. A second 8AN PTFE line runs through the tunnel parallel to the torque tube to the FPR on an aluminum mount near the brake master cylinder, with thermal insulation protecting hose and vacuum tubing from the exhaust. A SAE quick connect adapter connects the FPR to the OEM high pressure fuel pump using the stock feed line, and the OEM feed line from tank to engine bay is repurposed as the return.

Choose Your Kit

• Stainless Filter (20-1011-03): 10 micron stainless element, cleanable and reusable
• Microglass Filter (20-1011-05): 6 micron microglass element for the finest filtration

What You'll Feel

• A regulated, adjustable low pressure feed to the LT1 or LT4 high pressure pump instead of whatever the tank gives it
• OEM fuel pressure sensor retained for tuning, thanks to the inline tee in the feed
• The regulator and low micron filter the 20-1010 hanger requires, included rather than sourced separately
• Exhaust-proofed routing through the tunnel with thermal insulation
• E85-ready PTFE plumbing end to end

Features

• MPR-RA fuel pressure regulator with multiple high pressure ports and a fuel pressure gauge
• Check valve fuel filter with C7-specific billet filter mount and C7 FPR mount
• Inline tee preserving the OEM fuel pressure sensor for tuning
• 8AN PTFE feed hoses, 6AN PTFE hose, and 8AN filter adapter fittings
• SAE quick connect adapter for the OEM high pressure fuel pump connection
• Thermal insulating sleeve and stainless steel hardware

The Details

The C7's LT1 and LT4 run direct injection, so this kit does not replace the high pressure system; it feeds it correctly. The MPR-RA regulates the low side pressure delivered to the OEM HPFP, with the included gauge and adapter fittings provided for calibration, and the FPR's multiple high pressure ports leave room for the plumbing a specific build needs. The Radium 20-1010 hanger this kit serves eliminates both the in-tank regulator and the post-pump filter, which is why both arrive here. For two-pump builds, the 20-0937 dual pump add-on merges both outlets into the hanger's single 10AN ORB port, and this same plumbing serves that merged outlet.

Kit Includes

• MPR-RA fuel pressure regulator and fuel pressure gauge
• Check valve fuel filter in the selected element with C7 filter mount and C7 FPR mount
• 8AN PTFE fuel feed hoses, 6AN PTFE fuel hose, 8AN filter adapter fittings
• SAE quick connect HPFP adapter, thermal insulating sleeve, and stainless steel hardware
• NOT included: the 20-1010 fuel pump hanger, fuel pumps, and port injection components

Applications

• 2014-2019 Chevrolet Corvette C7, manual transmission only, with the Radium 20-1010 fuel pump hanger

Important Notes

• Not compatible with automatic transmissions due to fuel filter mounting interference; the 20-1010 hanger itself fits all C7 transmissions
