The simple answer is probably, maybe or no, depending upon a range of details – including your vehicle’s age, original emission system, condition and applicable regulations based upon where you live and.

No, if your vehicle is deemed to be an “emission-controlled vehicle.” Our products ARE NOT exempted from California’s anti-tampering and they MAY NOT be sold and installed on consumer vehicles.

What the state says: “Auxiliary fuel tanks are subject to California's anti-tampering laws. Installation of auxiliary fuel tanks on emission-controlled vehicles is prohibited unless the auxiliary fuel tanks have been evaluated and certified by the Air Resources Board.” In California, vehicles made in 1975 and later are subject to emissions testing.

Manufacturers began to offer OBD-II (On-Board Diagnostic II) systems as early as 1994. If your vehicle has an OBD-II system, it is an “emission-controlled vehicle” or ECV.

Your local / state regulatory agency may consider earlier vehicles to be an ECV - we suggest you conduct further research if you have questions.

It depends on your state regulations and inspection process, if any. In our experience, the LRA tanks, properly fitted to a well-maintained vehicle in good condition will not affect tailpipe emissions, generate error codes or lights under normal operating conditions.

If you make a long run up a steep trail on a hot day at high elevation (think Moab, Ouray, etc.) – you can expect a stock vehicle may experience tank contraction, vapor lock, diagnostic trouble codes, bubbling, burping and fuel discharge from the filler cap. An LRA tank in the same circumstances is likely to produce similar results.

In our experience, larger capacity fuel systems do not impact the vapor filters if properly designed and installed.

Overfilling of the fuel tank is a possible cause, along with long periods of vehicle positioning on high angle planes, causing fuel to overwhelm vent and line connections.

Perhaps, if your warranty claim is related to the engine control system, emission system or fuel system. It is also possible that the dealer or manufacturer would use presence of the aftermarket components to deny claims tied to other systems on the vehicle.

Yes, anything is possible as in the warranty question above. Consider, though, that the denial of a claim due to the mere presence of an aftermarket tank would also apply to installation of other aftermarket components such as: larger wheels/tires, lifted suspension, armor, roof racks and other additions that change braking, handling, center of gravity, etc.

Yes, anything is possible. If you are concerned with these potentialities, we suggest you pursue other alternative solutions for your fuel storage needs.
