Welcome to Fossil Free Fuel! We offer the latest in two tank straight vegetable oil conversion kits. Our systems are fully automated to ensure accurate temperatures and purging, and are also fully adjustable to accommodate different vehicle makes and models and give the driver full control of the system.

Fossil Free Fuel can make your dream vegetable oil conversion come true with our custom fabrication capabilities. From final heat exchangers to our own patented fuel filters and in-tank heat exchangers, we use only the highest quality parts in our systems. If you want your vehicle running well and looking good be sure to stop by our retail or online store.

Fossil Free Fuel installs kits by appointment only. We have been installing kits on diesel engines since 2003 and know the ins and outs of most makes and models out there. Bring us something new and we’ll take the time to fully understand the fuel system and fabricate whatever parts necessary for the install. Don’t be shy, we love a challenge.

Here at Fossil Free Fuel we’re driving for a greener tomorrow and hope you are too!
