Other than us, there are very few suppliers that provide propane conversions for modern fuel-injected vehicles and this is mainly because there are very few EPA and/or CARB-certified systems available. Many available DIY conversion kits are for carbureted vehicles or vehicles that have been downgraded from EFI to carburetion. Generally, even if these vehicles no longer require emission inspections, older carbureted on-road vehicles must continue to have all emission controls in place and fully functional. Shops that convert a vehicle with non-certified system may potentially be liable to penalties from the EPA or other authorities. However, shops are permitted to repair uncertified systems without risk of penalty.
Even though a properly configured injection conversion will run cleaner than the original gasoline engine, the lack of certification for universal systems means that they are generally non-compliant and are therefore recommended for "off-road" use only . Besides our own e-commerce site, the following sites offer DIY propane conversions for older carbureted vehicles only:
Before you buy any system, discuss your project with a local propane conversion company first for the following reasons:
- You should have your conversion inspected to that it meets propane safety codes in your jurisdiction and it best to work closely with the company that will be inspecting your work.
- If you experience any technical difficulties, they will be better able to assist you.
- They will be able to give you advice as to what systems meet emission regulation in your area. In the USA, the installation of a non-certified system may not comply with EPA or CARB regulations.
