The retainers permit hoses to be ran in a channel different than the OEM fuel and brake lines. They are typically installed underneath the RH side of the vehicle, as shown below.
However, they can also be installed underneath the LH side of the vehicle as well (see below).
The 5 included retainers are made from 6061 aluminum and anodized to resist oxidation.
1. This kit does not include aftermarket fuel lines. Maximum hose OD is 0.89" (22.6mm). NOTE: This is compatible with our 6AN, 8AN, and 10AN PTFE hose.
2. There is no way of determining exactly what size fuel lines can be used as there are many different types (rubber, braided, PTFE, aluminum, steel, etc).
3. Uses five OEM threaded holes and hardware with no drilling required.
