Over time, steel fuel tanks may experience corrosion or damage due to everyday use or exposure to road debris. It is important to regularly inspect the fuel tank for any signs of wear or leaks.

The fuel tank in the 1984 F350 is accessible for inspection and maintenance. It is typically located behind the rear axle, and the fuel pump and sending unit are often situated nearby.

The fuel tank has a 3-year warranty
The fuel tank in a 1984 F350 is located behind the rear axle. It has a capacity of 38 gallons and comes with a lock ring kit.
When it comes to fuel tank warranties, there are various options available depending on the manufacturer and the type of tank.

For instance, the 1984 F350's 16-gallon front steel gas tank comes with a 3-year warranty from the manufacturer's defects. This warranty covers the cost of replacing the steel fuel tank, but does not include labor costs or any other expenses arising from its use.
It's important to note that fuel tank warranties may have specific requirements and limitations. For example, some companies require that you contact the dealer where the unit was purchased, who will then request assistance from the manufacturer. Others may have specific shipping procedures or require proof of purchase and date of installation. It's always a good idea to carefully review the warranty terms and conditions before making a purchase decision.
Additionally, fuel tank warranties may not cover all components of the fuel system. For instance, some companies offer separate warranties for the fuel tank and the sending unit, fuel pump, or other components. It's important to understand what is and isn't covered under the warranty to ensure you're getting the protection you need.
In summary, a 3-year warranty on a fuel tank is a standard offering, but it's important to carefully review the terms and conditions to understand what is covered and what steps to take in the event of a claim.

The fuel tank switch/switch valve is problematic
The 1984 F350 is equipped with a dual-tank system, and issues with the fuel tank switch valve are not uncommon. The fuel tank switch valve, also known as the FTSV, is responsible for regulating the flow of fuel between the two tanks.
One of the most common issues with the FTSV is air leaking into the fuel lines. This can cause the engine to crank but not start, or to run for only a few seconds before dying. In some cases, air can be seen entering the fuel filter when the ignition is turned on and the fuel pump is engaged. This issue can be caused by a variety of factors, including a faulty water separator on older trucks, leaking O-rings around the injector plastic caps, or a break in the fuel pickups in the tanks.
Another potential problem with the FTSV is fuel leakage. If the valve is not functioning properly, it may allow fuel to leak out, leading to a decrease in fuel efficiency and potential safety hazards.
In addition to these issues, the FTSV can also become clogged or blocked, restricting the flow of fuel and leading to poor engine performance. This can be caused by debris or corrosion in the fuel lines, or by a faulty fuel pump.
To troubleshoot and resolve issues with the FTSV, it may be necessary to consult a mechanic or a Ford specialist. They can help diagnose the specific cause of the problem and recommend the appropriate repairs or replacements. It is important to address any issues with the fuel tank switch valve promptly to ensure the safe and efficient operation of your 1984 F350.
