Radium Engineering Top Feed Conversion Fuel Rail Mazda Eunos Cosmo (JC) Primary

Radium Engineering Top Feed Conversion Fuel Rail - Mazda Eunos Cosmo (JC) - Primary

This Radium Engineering high-flow primary fuel rail converts the 20B-REW three-rotor from the 1990-1995 Mazda Eunos Cosmo (JC) to top-feed injectors. The large-bore aluminium rail is black anodised for compatibility with all popular fuels including E85, and thermal insulating spacers and washers with stainless hardware limit heat transfer into the fuel (SKU 20-1120, replacing the discontinued 20-0464).

The supplied 14mm lower injector seats work with or without the OEM diffusers and use FKM O-rings suitable for boosted engines. Three 8AN ORB ports are provided, with the extra centre port available for accessories such as the OEM fuel temperature sensor (via Radium 14-0421), a pressure transducer or a Radium fuel pulse damper.

Note: Fuel injectors are not included. Injectors must be 34mm height with 14mm O-rings – 34.3mm (±1) O-ring spacing and 42.5mm (±1) overall length – such as Injector Dynamics 1050.34.14.14, 1300.34.14.14, 1700.34.14.14 or 2600.34.14.14. Port fittings are sold separately. Installation by a professional is recommended.
