How Do Ford Dual Fuel Tanks Work

Ford Dual Fuel tanks work by combining both diesel and gasoline fuel sources. The two fuels are stored in separate compartments, with the gasoline tank being located at the front of the vehicle and the diesel tank towards to rear. A special pump then draws fuel from both tanks depending on what is needed for a particular driving situation.

This allows drivers to take advantage of lower-priced diesel when available, while having access to additional power when necessary through the use of premium grade gasoline. The system also helps reduce emissions due to its ability to switch between fuels more quickly than traditional engines which require an engine shut down before switching fuels. Additionally, Ford’s dual fuel system offers increased safety as it can detect leaks or other problems that may occur in either tank and alert drivers accordingly.

The Ford dual fuel tank system is designed to provide a reliable and cost-effective alternative fuel solution. This innovative technology utilizes two tanks, one containing regular gasoline and the other with compressed natural gas (CNG). The engine runs on electricity generated by the CNG when it’s available, but automatically switches to gasoline when CNG isn’t present.

As a result, you get all the benefits of both fuels without having to maintain two separate systems.

Why Do Ford Trucks Have 2 Gas Tanks?

Ford trucks have two gas tanks for a couple of reasons. The first reason is so that the driver can switch between one tank and another in order to get better fuel economy. This allows drivers to use whichever tank has the cheapest price when they’re filling up, saving them money overall.

The second reason is safety – having two gas tanks means that if something happens to one of them, such as a leak or malfunctioning sensor, then you still have a backup should you need it while out on the road. Additionally, having two separate tanks gives drivers more options in terms of how much fuel they want to carry at any given time; for instance, if someone was going off-roading and needed extra capacity for longer trips without stopping too often for refueling. Ultimately, Ford trucks with two gas tanks provide drivers with greater convenience and peace of mind knowing that their vehicle will always be able to go the distance whenever necessary!

How Does a Dual Gas Tank Work?

A dual gas tank is a type of fuel system that offers drivers the option to choose from two different types of gasoline. This system allows drivers to fill up their vehicle with either regular unleaded or premium grade gasoline, depending on their needs and preferences. The tanks are usually located in the back of the car, near the rear wheel well.

Each tank holds its own level of fuel and can be switched between using an electronic switch or manual lever inside the vehicle’s cabin. When one tank runs out, simply flip the switch and you’ll instantly have access to your second tank full of gas. The advantage to this type of system is that it provides flexibility for drivers looking for different grades at different prices; it also ensures they always have enough fuel in case one source becomes unavailable due to local shortages or other circumstances.

Do Dual Fuel Tanks Have 2 Fuel Pumps?

Dual fuel tanks are a great solution for those who want to save money on their fuel costs and reduce their vehicle’s environmental impact. But do dual fuel tanks have two fuel pumps? The answer is yes, they do.

A dual fuel tank system requires two separate pumps—one for gasoline and one for diesel or other alternative fuels such as propane or natural gas. This ensures that the engine can receive the correct amount of each type of fuel at any given time, allowing it to operate efficiently regardless of what kind of gas or diesel is being used. It also allows drivers to switch from one type of fuel to another without having to stop and refuel multiple times throughout the day.

While dual-fuel systems may seem complex at first, they are actually quite simple in design, making them a breeze to install and maintain over time.

When Did Ford Stop Making Dual Fuel Tanks?

Ford stopped making dual fuel tanks in the late 1980s, when they began to focus on reducing emissions and increasing fuel efficiency. The dual-fuel tank was designed to run gasoline or E85 ethanol – a renewable, biodegradable alternative fuel source made from agricultural byproducts like corn and sugarcane – but with the push for higher standards of emission control, it became obsolete. Ford’s decision to discontinue the production of dual-fuel tanks was also due in part to its costliness compared to other solutions that could achieve similar results.

While these types of tanks weren’t particularly common among most cars at the time, some models offered them as an option until they were completely phased out by 1989. Other automakers followed suit shortly thereafter as well and eventually abandoned the technology altogether.

Ford Dual Fuel Tank Problems

Ford is known for its reliable vehicles, but owners of some models have experienced problems with their dual fuel tanks. Commonly reported issues include the tank not filling properly or leaking fuel while driving. In some cases, these issues can be caused by a faulty O-ring seal or loose connections in the fuel system.

If you are experiencing any of these problems with your Ford’s dual fuel tank, it is recommended that you get it inspected and repaired as soon as possible to avoid further damage to your vehicle.

How Do Dual Fuel Tanks Work on Semi Trucks

Dual fuel tanks on semi-trucks are designed to allow the truck driver to switch between two different types of fuel. The most common combination is diesel and propane, but some trucks use other fuels like biodiesel or natural gas. With dual fuel tanks, a driver can save money by running his truck on cheaper fuels when available, while still having the option to run it on diesel in case of emergency or availability issues with other fuels.

Dual fuel tank systems also provide an extra margin of safety since if one type of fuel fails for whatever reason, the truck can still be safely operated using the second type of fuel.

How to Fill Dual Fuel Tanks

Filling dual fuel tanks is an important part of maintaining your vehicle. The process involves adding both gasoline and diesel to the tank, depending on what type of engine you have in your vehicle. To fill a dual fuel tank, start by checking that both the gas and diesel caps are securely closed before filling up with either fuel.

Make sure to use only high-quality fuels approved for your specific engine type when filling up. Finally, add the appropriate amounts of each fuel according to your manual’s instructions and always remember to check your oil levels once you’ve filled up!


The Ford dual fuel tank system is a great way for drivers to save money on gas and reduce their environmental impact. With the ability to choose between gasoline or propane, it’s easy to find the most cost-effective fueling option for any trip. The separate tanks also provide an extra measure of safety by keeping both fuels away from each other, reducing the risk of any accidental combustion.

This system has been around since 2009, proving that its reliability and affordability make it a good choice for anyone looking to make their car more efficient and affordable.
