Simple & Fast Installation

1 - Find the location of your injectors

To install your future Flex Fuel E85 kit, you must first find the location of your injectors. Generally, the injectors are easily accessible on most vehicles and this does not require special skills in automobile mechanics. The injectors are positioned at the base of the injection rail closest to the cylinder head. FYI, the boom and injectors are always positioned opposite the exhaust manifold. If in doubt do not hesitate to contact us, we will accompany you...

2 - Plug in your Fuel Flex connectors

Once the location of your injectors found, it will be necessary to determine the type of connector. To do this, disconnect the battery, then a connector from your injector. Observe the shape of the male connector, as well as the female connector that corresponds to the injector and compare them to our different injectors connectors. Once the model is determined, all that remains is to select the type of connector for your kit. Namely, if you do not find the right type of connector, it is possible that your vehicle is equipped with an incompatible injection system (Direct Injection) or because it is not standard injector connector.

3 - Drive to ethanol

Once your E85 upgrade system is installed, you can refuel with E85 ethanol. However, it is best to change fuel gradually and make a full tank with 25% E85 ethanol for your first full tank. Subsequently, you can fill your tank with 50% E85, then 75% on the next and finally 100% E85 ethanol E85. This will progressively clean up your injection system and avoid potential engine operation problems during conversion. Noted that it is best to replace or clean the fuel filter after your first full 100% E85 ethanol, at least have it checked depending on the amount of miles on your vehicle..
