Installing an eFlexFuel kit is generally moderately easy, and the level of difficulty depends on the product version and how the installation is carried out.
If you are comfortable with basic engine bay work — such as accessing fuel injectors, connecting wiring harnesses, and routing cables — the installation is straightforward.
If you have no prior experience with automotive installations or are not comfortable using tools such as a multimeter, we recommend having the kit installed by a professional installer or completing the installation with the help of someone experienced.
