ORDER CANCELLATIONS

Important – No Guarantee of Cancellation Once Placed:
Orders are processed quickly, and our team does not directly control warehouse or vendor operations. If an order is in processing, packed, labeled, or transmitted to a vendor, cancellation may not be possible — even if your online order status has not yet updated.

If a cancellation cannot be completed:

The order will proceed as placed.

You may request a return under the above return policy, at your expense.

Custom/made-to-order items cannot be canceled once production begins. If no production has started and cancellation is requested within 24 hours, fees may be waived — but there is no guarantee.

Dealer Returns:

Dealer product returns mirror the standard retail policy. All return conditions, restocking fees, and non-returnable item rules apply.

Description

SMG Flex Fuel Conversion Kit – Fall 2025 Updated Edition

SMG’s Flex Fuel Conversion Kits are the benchmark for clean, reliable, and performance-oriented flex fuel integration. Every kit is 100% plug-and-play — no cutting, splicing, or guesswork required. We use only high-quality OEM-style electrical connectors, and each harness is wrapped in a continuous flexible braid for lasting durability and a professional, OEM-plus appearance.

Now Featuring Our All-New Hose Assemblies

For 2025, every SMG Flex Fuel Kit includes our redesigned PTFE fuel hose assemblies, featuring:

  • Machine-crimped ends for precision and long-term durability

  • Cam-lock connections for quick, secure, and leak-free installation

  • Ultra-smooth PTFE cores resistant to ethanol, methanol, and all modern fuel blends

  • Double-braided exterior that not only looks amazing but also ensures the best fit and function we’ve ever offered

These aren’t just hoses — they’re purpose-built components that elevate both performance and appearance. The result is a system that’s stronger, cleaner, and more confidence-inspiring than anything else on the market.

Performance You Can Feel

With minimal tools and roughly 30 minutes of installation time (depending on mechanical experience), you can equip your vehicle with the capability to safely run high-octane ethanol fuels.
With proper tuning, many modern engines have seen gains exceeding 30 wheel horsepower — making this one of the most powerful dollar-for-dollar upgrades available.

No other simple bolt-on delivers this kind of performance, reliability, and visual appeal.

Installation Details

  • Fully plug-and-play harness – no wire cutting or fuel line modification required

  • 100% reversible installation

  • Underhood mounting connects directly at your OEM fuel rails

     

     

Installation guides may be available for reference, but SMG does not provide installation or tuning support. Consult a professional installer or tuner if attempting a DIY install.
If your vehicle doesn’t have a vehicle-specific guide, a Universal PCM Pin-Out Reference is available for general wiring assistance.

Warranty & Professional Installation

Professional installation is required for warranty validation.
While performance parts typically do not include a warranty, SMG stands behind our craftsmanship — if your kit is installed by a verifiable professional, we’ll cover SMG in-house components for life (to the original purchaser).
All claims require return and testing by SMG before any authorization is issued.

Additional Notes

  • All kits now ship with the upgraded black PTFE hose assemblies as shown in product photos.

  • Installation process remains the same.

  • Tune required to enable ethanol sensor functionality and run ethanol fuels.
