Radium Engineering Fuel Hanger Feed Kit Mitsubishi Evo X

Radium Engineering Fuel Hanger Feed Kit Mitsubishi Evo X: Installation Guide

Is your Mitsubishi Evo X running out of fuel on the top end? Are you pushing more horsepower than the factory fuel system can handle? The stock fuel lines and filter weren't designed for heavily modified engines or high-octane race fuel. When you upgrade your turbo, injectors, or fuel pump, the factory feed system becomes a major bottleneck. This can lead to lean conditions, inconsistent fuel pressure, and potential engine damage under aggressive driving.

At CI Motorsports, we see it all the time. Customers come in with upgraded pumps and injectors, but they're still fighting fuel delivery issues. That's where a proper fuel feed upgrade comes in. The Radium Engineering Fuel Hanger Feed Kit with a Microglass Filter for the Mitsubishi Evo X addresses these exact problems. It replaces the restrictive factory fuel feed line with a high-flow setup designed to support serious power.

Installation Notes: Radium Engineering Fuel Hanger Feed Kit Evo X

Installing a fuel system component like this is a moderate to high difficulty job. It involves working with flammable liquids and specialized fittings. If you're not comfortable, we always recommend professional installation. Here’s what you need to know if you're tackling it yourself:

Tools You'll Need:

• Standard metric socket set and wrenches (8mm, 10mm, 12mm, 14mm, 17mm, 19mm)
• Line wrenches (for AN fittings, if applicable)
• Hose cutters (if any custom trimming is needed, though these are typically pre-cut)
• Floor jack and jack stands or a lift
• Fuel line disconnect tools (if needed for stock lines)
• Drain pan for fuel
• Fire extinguisher (safety first)
• Shop towels/rags
• Eye protection and gloves
• Torque wrench

Time Estimate:

Expect this installation to take anywhere from 4 to 8 hours for an experienced DIY mechanic. First-timers might need longer, especially when dealing with routing lines and making sure everything is sealed correctly. Take your time. Rushing leads to mistakes.

Difficulty:

Moderate to High. This isn't a bolt-on air intake. You're working with the heart of your car's fuel delivery. Precision and attention to detail are critical to prevent leaks and ensure proper function.

General Steps (Outline - always refer to Radium's specific instructions):

• Safety First: Disconnect the battery. Relieve fuel system pressure. This is critical. Consult your factory service manual for the proper procedure (often involves pulling a fuel pump fuse and running the engine until it stalls).
• Access: You'll need to access the top of the fuel tank (usually under the rear seat) and the existing fuel line routing under the car and into the engine bay. Lift the car safely.
• Drain Fuel (Optional but Recommended): If your tank is full, it's a good idea to drain some fuel to reduce spillage when disconnecting lines.
• Remove Stock Line: Carefully disconnect the factory fuel feed line from the fuel hanger outlet and trace it all the way to the engine bay. Expect fuel spills. Have your drain pan ready.
• Install Radium Feed Line: Route the new Radium PTFE feed line from the fuel hanger to the engine bay fuel rail. Pay close attention to routing to avoid kinking, rubbing, or interference with moving parts. Use any included P-clips or mounting hardware.
• Install Fuel Filter: Mount the Radium fuel filter using the provided bracket in the designated location. Connect the feed line to the filter and the filter to the engine bay fuel rail. Ensure flow direction is correct.
• Connect Fittings: Use appropriate line wrenches to tighten all AN fittings. Do not overtighten; AN fittings seal differently than NPT. Consult Radium's torque specs or general AN fitting guidelines.
• Double Check: Inspect all connections. Ensure no lines are kinked or rubbing. Reconnect the battery.
• Prime and Test: Cycle the ignition several times without starting the engine to allow the fuel pump to prime the system and build pressure. Check for leaks meticulously. Start the engine and continue to check for leaks. Address any leaks immediately.

Common Mistakes to Avoid:

• Not relieving fuel pressure: This is dangerous and will result in significant fuel spray.
• Improper AN fitting technique: Cross-threading or overtightening AN fittings can damage them and cause leaks. Use two wrenches: one to hold the hose end, one to tighten the nut.
• Kinked or pinched lines: Route lines carefully, avoiding sharp bends. A kinked line restricts flow.
• Incorrect filter orientation: Fuel filters have a specific flow direction. Make sure it's installed correctly.
• Forgetting to replace O-rings or seals: Any connection that uses a crush washer or O-ring needs a fresh one for a proper seal.
• Not checking for leaks: This is probably the most critical step. A small drip can turn into a serious problem.

Fitment: Radium Engineering Fuel Hanger Feed Kit

This specific Radium Engineering Fuel Hanger Feed Kit with Microglass Filter is designed for:

• Mitsubishi Lancer Evolution X (Evo X): All models from 2008 to 2015.

What it Does NOT Fit: This kit is specific to the Evo X chassis. It is not designed for other Lancer models, previous generation Evolutions (Evo I-IX), or any other vehicle make/model. Always confirm your vehicle's exact year, make, and model before ordering. If you have any questions about fitment, contact the CI Motorsports team before you buy.

Maintenance and Care

The main maintenance item for this kit is the fuel filter element. Radium's microglass filter elements are highly effective, but they do have a service life. Depending on fuel quality and usage (street vs. race), it's a good practice to inspect and consider replacing the filter element every 12-24 months or 15,000-30,000 miles. For race cars running E85, you might want to check or replace it more frequently. A clogged filter will restrict fuel flow, just like your factory setup.

Regularly inspect the PTFE hoses for any signs of wear, rubbing, or leaks. While PTFE is highly durable, physical damage can occur. Make sure all fittings remain tight, especially after the first few heat cycles.

Customer Considerations: Who Needs This Upgrade?

This Radium Engineering Fuel Hanger Feed Kit is for a specific type of Evo X owner:

• Serious Performance Enthusiasts: If you're running an upgraded turbo, larger injectors, or a high-volume fuel pump, this kit is essential to support your power goals.
• E85 Users: E85 requires significantly more fuel volume than gasoline. The higher flow capacity of this kit is critical for E85 setups.
• Track Day/Race Car Builders: For cars that see high RPMs and sustained load, consistent and ample fuel delivery is non-negotiable.
• Anyone Tired of Fuel Pressure Drops: If your datalogs show fuel pressure dropping at high RPMs or boost, this kit will address that bottleneck.

Who might skip it? If your Evo X is completely stock and you plan to keep it that way, the factory fuel lines are sufficient. This is a performance upgrade for modified vehicles.
