Radium Fuel Hanger, 89-05 Mazda MX-5, Pumps Not Included

Application: Mazda MX-5 NA (1989-1997) and NB (1999-2005)
Part Type: Billet aluminium fuel pump hanger – pumps not included
Part Number: 20-1020

The Radium Fuel Pump Hanger replaces the factory in-tank fuel pump module on the 1989-2005 Mazda MX-5 and supports one or two aftermarket fuel pumps. The OEM fuel level sensor is reused and no modifications are needed under the fuel pump access cover.

The OEM internal tank baffle is retained, and a one-piece anodised aluminium collector box with two one-way fill valves (355 LPH each) keeps fuel around the pump inlet(s), refilled by fuel returning from the pressure regulator. Anodised billet extension brackets suit all tank variants, including an extension mount for later models with deeper tanks.

Key Features

• Single or Dual Pumps: Supports one or two aftermarket pumps
• OEM Sender Retained: Factory fuel level sensor reused
• Starvation Prevention: OEM baffle retained plus collector box with two 355 LPH one-way fill valves

• Year-Specific Fittings: SAE quick connect barbs (89-97) and SAE banjo fittings (99-05) included

• 1989-1997: the OEM FPR is retained on the fuel rail
• The OEM post-pump filter is not eliminated
