Description

Radium Primary Top Feed Conversion Fuel Rail - Mazda Cosmo JC (20B-REW)

Application: Mazda / Eunos Cosmo JC (1990-1995) - 20B-REW
Part Type: Top feed conversion primary fuel rail
Part Number: 20-1120

The Radium Engineering high-flow primary fuel rail suits the 20B-REW three-rotor engine found in the 1990-1995 Mazda/Eunos Cosmo. The aluminium rail is anodised black for compatibility with all popular fuel types including E85, and its large internal bore supports all necessary engine power requirements.

Thermal insulating spacers and washers are included with stainless steel hardware to help prevent heat conducting into the fuel. The included 14mm lower injector seats are designed to work with or without the OEM diffusers in place, and use FKM O-rings suitable for boosted applications. Three 8AN ORB ports are provided - the extra centre port accepts accessories such as the OEM fuel temperature sensor, a pressure transducer or a Radium fuel pulse damper.
