Our auxiliary tanks are NOT gravity feed. We feel this is not the best option for a few reasons. Our competitor’s gravity feed fuel system may be cheaper to buy but that is the only benefit. There are a lot of pitfalls to gravity feed, here are a few; can overfill stock tank and leak on the ground, on most new trucks it will set a check engine light because it keeps the stock tank full all the time, will not let the mileage calculator work (miles to go and miles per gallon). The biggest issue we see with the gravity feed is if the fuel line breaks from an accident, age or wear and tear the fuel is going to leak on the ground. Fuel on the ground is an environmental and fire problem that cheap in the long run is not worth. Also more food for thought; when was the last time you saw a vehicle come from the factory with gravity feed? I think it may have been the model T and the truck you are driving is not a model T.

No, our tanks are DOT certified & follow EPA regulations for DIESEL FUEL ONLY. The reason for this is all our tanks are vented to the atmosphere. All 1996 and newer gasoline pickup trucks are equipped with a sensor in the tank for emission.
