NOTE:
· YUZOX should only be installed by a professional. Contact the nearest service station for assistance.
· We recommend unplugging the battery in your car prior to the instillation of Yuzox. Once installed, reconnect your battery. We ask you do this because certain cars have a preset air to fuel ratio and it must be recalculated once Yuzox is installed.

For Rubber Fuel Injection Hoses
1) Remove the hose from its connection with the fuel injector.
2) Connect the end of the hose to one end of Yuzox.
3) Connect a short length of hose to the other end of Yuzox and then to the Fuel Injector.
4) Apply hose band and firmly tighten with a screwdriver.
5) In order to stabalize, band the hose together with other hoses as much as possible.
* When removing the hose, please be careful as gasoline may leak. Apply a towel before removing the hose. Make sure that the engine is off, and that there is no fire, lit cigarettes or the like neaby as some gas may come out of the cut fuel line.

For Hard Injection Hoses such as Teflon and Polyethlene
1) Cut the fuel injection hose where there is enough space to insert YUZOX.
2) Peel off the outer cover of the hose for approximately 3 inches.
3) Use pipe nut: apply nut to the hose, connect with the pipe nut and apply packing material.
4) Inset the nipple of the pipe nut into short cut rubber hose.
5) Connect the rubber hose to YUZOX.
6) Make sure all screws and nuts are firm.
