Radium Engineering Fuel Hanger (Pumps Not Included) - Mazda MX-5 (NA / NB)
This Radium Engineering fuel pump hanger completely replaces the factory in-tank pump module on the Mazda MX-5 NA and NB and accepts one or two aftermarket pumps (pumps sold separately, SKU 20-1020). It fits under the fuel pump access cover with no modification and reuses the OEM fuel level sensor.

Miata Fuel Sender Upgrade using Radium Engineering Billet Kit with beefy terminal connections
A one-piece anodised aluminium collector box (1.85L) traps fuel around the pump inlets, with two one-way fill valves (355LPH each) and constant regulator return flow keeping it full during hard cornering. Billet extension brackets suit every tank variation from 1989 to 2005, with an extended sensor mount for the deeper late-model tanks.
Note: Pumps are not included; the hanger suits 39mm OD pumps including the AEM 50-1200, Walbro GSS342 and F90000267/274/285 (TI E5LM staging with 20-0798 recommended). 1989-1997 cars retain the OEM regulator, while 1999-2005 cars need an aftermarket FPR such as Radium 20-1022. The OEM post-pump filter is retained and upgraded wiring is recommended. Installation by a professional is recommended.
