That’s where the DeatschWerks 6-618 Fuel Hose Kit comes in.

Designed specifically for the:

• 2013–2020 Subaru BRZ
• 2017–2020 Toyota 86
• 2013–2016 Scion FR-S

…the DeatschWerks 6-618 Fuel Hose Kit upgrades critical fuel delivery components to support higher fuel flow, ethanol compatibility, and increased reliability under performance driving conditions.

Because nothing ruins a dyno session faster than fuel starvation and panic.

What Is the DeatschWerks 6-618 Fuel Hose Kit?

The DeatschWerks 6-618 kit is a performance fuel hose upgrade engineered for the FA20-powered BRZ, FR-S, and Toyota 86 platform.

It replaces restrictive or aging factory fuel hoses with higher-quality performance-oriented components capable of handling:

• Increased fuel pressure
• Higher fuel volume
• Ethanol-based fuels like E85
• Forced induction setups

This becomes especially important for:

• Turbocharged builds
• Supercharged setups
• Flex fuel conversions
• Track-driven cars
• High-horsepower naturally aspirated builds

Because factory fuel systems were not designed for “bro I turned the boost up another 6 psi” engineering strategies.

Why Fuel Hose Upgrades Matter on the FA20 Platform

The FA20 engine responds extremely well to:

• E85 tuning
• Turbocharging
• Aggressive ignition timing
• Higher fuel flow

But ethanol-based fuels demand significantly more fuel volume than traditional gasoline.

That means:

• More pressure
• More flow
• More strain on the fuel system

A weak or aging hose setup can lead to:

• Fuel pressure inconsistencies
• Leaks
• Heat degradation
• Fuel starvation
• Dangerous lean conditions

And lean boosted FA20 engines have a remarkable ability to become expensive paperweights almost instantly.

Key Features of the DeatschWerks 6-618 Fuel Hose Kit

Vehicle-Specific Design

Unlike universal fuel hose setups that require half a hardware store and emotional support, the 6-618 kit is designed specifically for:

• Subaru BRZ
• Scion FR-S
• Toyota 86 chassis

That means:

• Proper fitment
• Cleaner installation
• Simplified routing
• Reduced installation headaches

Which is refreshing in the aftermarket world.

E85 Compatibility

One of the biggest reasons enthusiasts upgrade fuel systems is ethanol compatibility.

The DeatschWerks hose kit is engineered to support:

• E85
• Flex fuel setups
• Modern ethanol-blended fuels

This is critical because ethanol can degrade lower-quality rubber fuel components over time.

Especially on older modified cars where previous owners believed “maintenance” was mostly a rumor. And? If you live in California, don’t forget about the new E85 conversion law.

Improved Fuel Flow

Higher horsepower requires greater fuel delivery capacity.

This hose kit helps support:

• Larger injectors
• High-flow fuel pumps
• Return-style fuel systems
• Forced induction upgrades

Whether you’re building:

• A street car
• Drift car
• Track build
• Time attack setup

…fuel delivery consistency matters.

A lot.

Perfect Supporting Mod for Forced Induction

The BRZ/FR-S/86 platform exploded in popularity once turbo and supercharger kits became widely available.

Popular setups include:

• Jackson Racing
• HKS
• Greddy
• Vortech
• Edelbrock
• Precision turbo systems

But many enthusiasts focus entirely on:

• Horsepower numbers
• Dyno graphs
• Blow-off valve noises loud enough to alert wildlife

…while forgetting fuel system reliability entirely.

That’s how engines leave the chat unexpectedly.

The DeatschWerks 6-618 kit helps create a safer and more stable fuel delivery foundation before increasing power.

Why DeatschWerks Is Trusted in the Performance Industry

DeatschWerks has become one of the most recognized names in aftermarket fueling because they focus heavily on:

• High-flow fuel systems
• Injector technology
• Ethanol compatibility
• Motorsports reliability

Their products are commonly found on:

• Street builds
• Drag cars
• Drift cars
• Time attack vehicles
• Professional motorsports platforms

And unlike random no-name fuel parts from questionable online listings, properly engineered fuel components are not the place to gamble.

Fuel leaks near turbochargers are a terrible way to discover personal growth.

DeatschWerks 6-618 Fuel Hose Kit Installation Notes

The DeatschWerks 6-618 Fuel Hose Kit is designed as a direct-fit upgrade, but professional installation is always recommended for:

• Fuel system modifications
• Ethanol conversions
• Pressurized fuel systems

Especially if:

• Larger injectors are installed
• An upgraded pump is added
• Flex fuel tuning is planned

After installation, proper ECU calibration becomes essential.

Because adding fuel system upgrades without tuning is basically giving your ECU a nervous breakdown.

Final Thoughts

The Subaru BRZ, Scion FR-S, and Toyota 86 remain some of the best modern enthusiast platforms because they respond incredibly well to proper modifications.

But reliable horsepower always starts with:

• Fuel delivery
• Proper tuning
• Supporting upgrades

The DeatschWerks 6-618 Fuel Hose Kit helps reinforce one of the most critical systems on any performance build, especially for:

• E85 conversions
• Turbocharged setups
• Supercharged applications
• High-performance street cars

Because reliable fuel delivery is significantly cooler than explaining rod knock to your friends in a parking lot.
