Ford F-350 Fuel Tank

How to Care for the Ford F-350 Fuel Tank: 3 Essential Tips

The maintenance-free design of the fuel tank in your the Ford F-350 means that it can function for the rest of its life without the need for human intervention. But there are ways for you to take care of it to prevent it from getting damaged prematurely. While they are designed to be tough enough to safely contain gasoline, fuel tanks are still vulnerable to wear and can spring a leak or contaminate the fuel in the process. Keeping the Ford F-350 fuel tank in top shape is quite easy, and most of the steps circle around what you put through the fuel nozzle. Below are some key steps to follow in maintaining the fuel tank in your Ford truck:

  • Always keep the fuel tank full.

One of the easy ways you can maintain the tank in good running condition is to keep it topped up at all times or, at the very least, keep it from running low. Unbeknownst to many, the heat from the engine can actually travel up to the fuel lines and into the fuel tank, and gas inside the tank helps keep the temperature down. So when the tank is near empty, the temperature inside it can quickly rise up, potentially damaging itself in the process.

  • Don't get gas while the station's supply is being refilled.

Gas stations store fuel in large storage tanks, and every time they replenish, rust and debris that have settled at the bottom of the tank get stirred up. These contaminants can then easily enter your fuel tank along with the gas, so as much as possible, avoid lining up at the gas station while it's refilling.

  • Check the filter on a regular basis

Even if you keep the tank topped up with a high-quality fuel, microscopic particles will still manage to get into the tank. Thankfully, the fuel filter catches these impurities before they leave the tank. However, these contaminants will eventually build up over time and clog the filter. Ideally, the fuel filter should be replaced every 2 years or 100,000 miles, whichever comes first. But if the truck starts to show signs of clogging in the fuel lines, such as stalling and hard starting, the filter needs to be replaced immediately.

  • Helpful Tips When Installing a New Ford F-350 Fuel Tank

    Installing a new fuel tank on the Ford F-350 is a rare occurrence, but if the tank has sprung a serious leak or has been contaminated with impurities, then it needs to go. And while replacement of the Ford F-350 fuel tank is a task that is best suited for professional mechanics, it is possible for you to do the installation yourself and save a lot of money (as well as gain experience) in the process. Replacing the fuel tank can be a difficult yet rewarding task. Here are some important tips to follow when installing this crucial component into your truck:

    Tip #1: Drain the tank.

    Unless you want to create a dangerous mess, you need to drain both the fuel tank and the fuel lines of gas before starting. Begin by removing the gas filler cap to relieve pressure in the tank and disconnect the battery cable from the negative terminal. Next, detach one of the fuel lines from the tank and let the fuel drain out from there. You can also use a hand siphon pump to drain all the fuel through a hose in the filler neck. But whatever option you take, make sure that the gas drains to a safe fuel container. You can choose to reuse the gas, but if it is tainted with contaminants, it needs to be disposed of properly.

    Tip #2: Clean up the mounting area.

    Unless you just recently purchased your truck, you have to clean the space where your old fuel tank was installed before putting in the new one. Any dirt left on the mounting area can contaminate the new tank, so make sure to thoroughly clean the area before starting the installation. In addition, it is also recommended to replace the retaining straps holding the fuel tank in place, particularly if they are rusted or damaged.

    Tip #3: Do not weld or solder the fuel tank.

    Even if the fuel tank is empty, the fuel gum that lines the inside of the tank can still catch fire due to extreme heat that can be caused by welding or soldering. Remember that the clamps that normally secure the tank are more than enough to hold it in place, so such methods may no longer be necessary. But if welding or soldering tank into the chassis is truly important, have it done by a professional to minimize the risk of fire.
