• Planning is needed for some vehicles: If you drive a hybrid or electric vehicle, note that you’ll need to add an external fuel tank, as it taps into your main tank’s supply.
• Mind the heat: You must ensure nothing flammable is near the exhaust or heater body during installation, as it gets seriously hot during operation.
