Radium Fuel Pump Hanger | 2014-2019 Chevrolet Corvette C7 (20-1010)

The C7's LT1 and LT4 are direct injected, which means the low pressure side is the ceiling almost nobody thinks about until it bites.

The Radium Engineering fuel pump hanger for the 2014-2019 Chevrolet Corvette C7 replaces the stock fuel pump assembly with a drop-in unit requiring no cutting or modification of the vehicle. It ships configured for one aftermarket pump with an integrated collector box, filter socks, and high current electrical hardware, reuses the OEM crossover jet pump siphon, and expands to two staged pumps with the separate 20-0937 dual pump add-on. Gasoline, methanol, and E85 compliant. Pumps are not included.

What You'll Feel

• Steady supply under cornering load from a collector fed three ways: crossover scavenge, regulator return, and twin 355 LPH one-way fill valves
• Headroom to add a second staged pump later without replacing the hanger
• Brushless pump capability, with DW440, DW810, Protec 11928, and Fuelab 49614 supported using the 20-0441 clamp
• Clean AN plumbing from the top plate with low profile adapters provided

Features

• Fuel pump outlet tapped 10AN ORB (7/8in-14) female with an 8AN male fitting included
• Fuel return inlet tapped 8AN ORB (3/4in-16) female with a 6AN male fitting included
• Partially assembled hanger with collector box, filter socks, two styles of wiring harness, and an electrical parts kit for external wiring
• Hermetically sealed stainless electrical studs, non-conductive acorn nuts, ETFE in-tank wiring
• Compatible pumps: AEM 50-1000 and 50-1200, Walbro GSS342, F90000267/274/285, F90000295, Ti E5LM, DW440, DW810, Protec 11928, Fuelab 49614
• High flow check valve included for the F90000295 and E5LM, which lack integrated check valves

The Details

This hanger eliminates both the in-tank fuel pressure regulator and the in-tank post-pump filter, so every installation requires an aftermarket regulator and a low micron filter downstream. The Radium fuel hanger plumbing kit for the C7 (20-1011-03 or 20-1011-05) supplies both along with the full tank-to-engine run, and Radium specifically recommends a check valve filter for this application. Single pump installs can reuse the OEM fuel pump wiring, though upgraded wiring is recommended for full pump output; multi-pump builds need dedicated relays and fuses per pump. For two pumps, add the 20-0937 dual pump add-on, which serves both the C7 and the earlier mid-mount Corvette hanger.

Kit Includes

• Partially assembled fuel pump hanger with collector box
• Two styles of wiring harness and an electrical parts kit for external wiring
• Filter socks and all hardware to install one pump into the hanger
• Low profile 8AN male outlet fitting and 6AN male return fitting
• NOT included: fuel pump(s), fuel pressure regulator, low micron fuel filter, the 20-0937 dual pump add-on, and the 20-1011 plumbing kit

Applications

• 2014-2019 Chevrolet Corvette C7, all trims

Important Notes

• An aftermarket fuel pressure regulator and low micron fuel filter are required on every installation; both are included in the 20-1011 plumbing kits
• The 20-1011 plumbing kit is compatible with manual transmissions only due to fuel filter mounting interference; the hanger itself fits all C7 transmissions
• Brushless and 41-43mm body pumps require the Radium 20-0441 pump clamp, sold separately
