Why do old Fords have two gas tanks?
Many older Ford vehicles, particularly those from the 1960s and 1970s, were equipped with two gas tanks. This unique feature was not just a design quirk, but served a practical purpose for Ford owners at the time. The reason behind this dual-tank setup is rooted in the engineering and fuel efficiency considerations of the era.
The Rationale Behind Two Gas Tanks
The primary reason Ford included two gas tanks in many of its older models was to improve fuel efficiency and range. During the 1960s and 1970s, when gas prices were relatively low, Ford engineers sought ways to maximize the distance a vehicle could travel on a single tank of fuel. By incorporating a second tank, they were able to increase the total fuel capacity and extend the driving range of these Ford models.
Additionally, the two-tank design provided a backup option in case one of the tanks ran dry. This was particularly useful in rural areas or on long road trips, where finding a gas station might have been more challenging. Drivers could simply switch to the other tank to continue their journey without the risk of running out of fuel.
How the Two-Tank System Worked
- The two gas tanks were typically located on either side of the vehicle, with one tank on the driver's side and the other on the passenger side.
- Drivers could manually switch between the two tanks using a selector valve or switch, allowing them to balance the fuel consumption and maintain a more even weight distribution in the vehicle.
- The tanks were often of different sizes, with one being the primary tank and the other serving as a smaller auxiliary tank.
- The fuel lines from both tanks would converge at the fuel pump, allowing the engine to draw from either tank as needed.
While the two-tank system provided benefits in terms of fuel efficiency and range, it also added complexity to the vehicle's design and maintenance. Drivers had to be mindful of switching between tanks and monitoring fuel levels in both tanks to avoid running out of gas unexpectedly.
The Decline of the Two-Tank System
As fuel efficiency standards and engine technology improved over time, the need for the two-tank system became less critical. Newer Ford models, as well as those from other automakers, typically feature a single, larger fuel tank that can provide sufficient range without the added complexity of a dual-tank setup.
Today, the two-tank design is largely a relic of the past, but it remains an interesting piece of automotive history that highlights the engineering challenges and solutions of a bygone era.
What does a secondary tank do?
Defining and Understanding the Purpose of Secondary Containment Tanks. A secondary containment tank is a structure or device designed to contain leaks, spills, and overflows that may occur within a primary storage vessel.
Do dual fuel tanks have 2 fuel pumps?
The two main dual fuel pump designs are series and parallel. A series design places two fuel pumps inline in a common fuel line. A parallel system has pumps working in two separate fuel lines that commonly merge farther up the fuel system at a 'Y' connec- tion.
Why did Ford use two fuel tanks?
They were fitted there because they fit, only room on a tilt cab, you could fill both at the same time if at a real truck stop, a big advantage. Also fuel weights about 6.3 per gallon, so two tanks divides the weight.

What's the point of dual gas tanks?
Some vehicles, particularly larger trucks and vans, may have dual fuel tanks installed. Having two fuel tanks allows for increased fuel capacity and extended range between refueling stops.
What is the purpose of the auxiliary tank?
Auxiliary fuel tanks: These tanks are designed to supplement the existing fuel tank of a vehicle or equipment. They are typically installed in the bed of a truck and used in addition to the factory-installed tank and provide extra fuel storage capacity.
Is dual fuel better than just gas?
So, is a Dual Fuel Range Better than Just Gas? Yes! A dual fuel range offers the benefits of both gas cooktops for precise temperature control and electric ovens for even baking.
What engine has 2 cylinders?
A straight-twin engine, also known as an inline-twin, vertical-twin, inline-2, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft.
What is a secondary fuel tank?
AUXILIARY FUEL TANKS are defined by the Vehicle Equipement Safety Commission as an additional fuel tank and any other componets attached directly thereto designed to supplement the vehicle's fuel carrying capability beyond that provided by the vehicle manfacturer.
