Upgrading the fuel system on an Evo X can be a lot of trouble if not thought out completely. It is very difficult to upgrade only one component without consideration for the others. The restrictive return line, the in-tank venturi jet pump system, the integrated fuel filter. All these, and more, create a complicated system to modify for high performance. If not thought out properly, issues will show up on the dyno, such as inconsistent fuel delivery, overly high fuel pressures, fuel starvation and more.
The Radium Complete Fuel Delivery System for the Evo X solves all these issues in one complete kit. Every details has been thought out and tested in real world conditions. The result is a bolt-on kit that performs as expected, capable of meeting the fueling needs of highly modified 4B11T engines.
This comprehensive kit includes everything required to construct a high performance fuel delivery system for the EVO X. The title photo at the top of the this page shows the kit contents. The Radium fuel pump hanger, feed line kit, fuel rail, and pressure regulator completely replace the restrictive OEM fuel system with a setup capable of supporting well over 1,000hp. At the heart of the system is the Radium EVOX fuel pump hanger.
From the fuel pump hanger, the feed line kit passes fuel through a Radium in-line fuel filter using prefabricated -8AN PTFE hoses. The filter is mounted to the chassis under the car using a specially designed bracket that does not require any cutting or drilling for installation.
Kit comes standard with twin Walbro 450 pumps (Walbro F90000274 - 20-0642-02), a black Fuel Pressure Regulator (20-0623-00), and a stainless steel fuel filter (20-0246-03).
