Frequently Asked Questions (FAQ)

Are gravity-feed in-bed diesel fuel tanks legal?

Yes, gravity feeding of diesel fuel is legal, according to:

FMCSA regulation 393 Subpart E – Fuel Systems

  • § 393.65 All Fuel Systems.

(d) Gravity or syphon feed prohibited. A fuel system must not supply fuel by gravity or syphon feed directly to the carburetor or injector.

  • § 393.67 Liquid fuel tanks.

(5) Fuel withdrawal fittings. Except for diesel fuel tanks, the fittings through which fuel is withdrawn from a fuel tank must be located above the normal level of fuel in the tank when the tank is full.

Here at Titan Fuel Tanks, we have made every effort to make sure our tanks comply with the appropriate regulations. Our gravity-feed systems only supply diesel fuel through the fill neck hose. In other words, our systems deliver diesel fuel into the existing diesel fuel tank maintaining normal vehicle operations and safety requirements.

Note: The only gravity-feed fuel systems we provide are for Diesel fuel tanks.

How much more range will I get with a TITAN Fuel Tank?

A TITAN Fuel Tank will just about double the range of most popular crew cab applications. For example, the stock tank on a GM Crew Cab Short Bed truck is 26 gallons; the TITAN replacement tank is 52 gallons. A Ford Crew Cab Long Bed comes with a 34 gallon tank; the replacement TITAN Fuel Tank holds 67 gallons. For extended cab and other applications, you can expect at least a 65% to 90% increase in capacity and corresponding range.

Will my fuel gauge be accurate?

Yes. Your analog fuel gauge will work the same with the TITAN Fuel Tank as it did with your original stock equipment tank.

Will my Driver Information Center (DIC) computer work the same?

No. The DIC computer will not be accurate.

Is there a way to fix the DIC computer?

Depending on the application the tank size can be recalibrated by a local dealer or using EFI Live. Call our Customer Service for assistance.

Can I install a TITAN Fuel Tank on my gasoline-powered truck?

We offer two products that are approved for use with gasoline.
The first is our Sidekick, it is an in-bed 15 gallon transfer tank. It will fit in most truck beds including smaller trucks like the Ranger and Tacoma. The SideKick is perfect as an emergency fuel storage for those traveling long distances or for those that simply want to be prepared. It also works great refueling motorcycles, ATVs, lawn mowers and other equipment. It includes a free transfer pump.

We also have the Trail Trekker Transfer Tank for all Jeep (YJ, TJ & JK)Wranglers that holds 12 gallons and includes a free transfer pump.

How much does the tank weigh?

The TITAN short-bed tank models weigh an average of 45 pounds (without the bracket hardware). The TITAN long-bed tank models weigh just a few pounds more than the short-bed tank models. This means more capacity with less weight and easier installation. The TITAN In-Bed tank weighs about 51 pounds.

How difficult is installation?

We've made every effort to make installation as simple as possible. The TITAN Fuel Tank fits in place of your original tank. We include all the necessary parts and detailed instructions. Generally speaking, installation entails removing the stock tank, moving the sending unit to the new TITAN Tank, reattaching the fuel lines, and bolting in the new tank. Your TITAN dealer can help you with installation.

How long does installation take?

Between 2-4 hours depending on your expertise. We've seen TITAN Fuel Tanks installed in 45 minutes.

Is the TITAN Fuel Tank as durable as the original stock equipment tank?

More durable and better warrantied. Most stock (or original equipment) tanks are relatively thin and made of materials like Linear Polyethylene. TITAN Fuel Tanks are made of High-Density Cross-Linked Polyethylene (XLHDPE), which is bonded molecularly. Also, the nominal thickness of all TITAN Tanks is 1/4th of an inch. TITAN Fuel Tanks are so tough that they are backed by a lifetime warranty.

Does the TITAN Fuel Tank hang down lower than the stock tank?

For most applications the TITAN hangs about 1 to 2½ inches lower than the stock tank. Usually the difference is negligible.

Do I need the TITAN Shield?

The TITAN Shield, is incredibly tough. It fits over the bottom of the tank, providing the underside with a rock shield. We recommend it for owners who go off-road, or for an extra layer of protection.

How quickly could you ship a TITAN Fuel Tank to me?
