Radium Engineering Fuel Rail Plumbing Kit | 2008-2015 Mitsubishi Evo X (20-0112-PK)

A billet rail is only half the job; connecting it to the factory feed line cleanly is the other half.

Adapting an aftermarket rail to the Evo X's OEM fuel line and regulator usually means hunting down a pile of one-off fittings. The Radium Engineering Fuel Rail Plumbing Kit solves that in one box, pairing a pre-fabricated 24" 6AN PTFE hose with the exact adapters to connect the factory feed line at the firewall to the Radium Evo X fuel rail while reusing the OEM fuel pressure regulator. Everything arrives ready to bolt on. One kit, zero guesswork.

What You'll Feel

• An afternoon install instead of a fitting scavenger hunt
• Leak-free confidence from PTFE hose and O-ring sealed connections
• Factory drivability retained by reusing the OEM regulator
• A clean engine bay with purpose-made hose lengths, not coiled excess

Features

• Designed for the Radium Evo X fuel rail (20-0112-12, sold separately)
• Connects the factory feed line to the rail and reuses the OEM fuel pressure regulator
• Pre-fabricated 24" 6AN PTFE hose with 45-degree and 90-degree swivel hose ends
• 5/16" SAE to 6AN male fitting adapts the incoming factory line near the firewall
• 8AN ORB to 6AN male fitting adapts the hose to the rail inlet, with an FPR adapter for the outlet port and an 8AN ORB plug for the top port

The Details

The kit works with the factory quick-connect feed line: the 5/16" SAE adapter clicks onto the OEM line near the firewall and converts it to 6AN male, the PTFE hose spans to the rail, and the 8AN ORB to 6AN fitting seals into the rail inlet port. At the outlet, the two-piece FPR adapter lets the factory regulator bolt to the Radium rail in its stock orientation, keeping the OEM return and vacuum reference untouched. The 8AN ORB plug closes the rail's top port unless you choose to run a damper or gauge there instead. PTFE hose matters here because it is impervious to modern fuels, including ethanol blends, and will not degrade or smell like rubber lines can. This kit contains plumbing only; the fuel rail itself is sold separately.
