Ford F-250 Super Duty Fuel Tank

Maintenance Tips for Ford F-250 Super Duty Fuel Tank

Our interactions with the Ford F-250 Super Duty fuel tank are often limited to refueling at the gas station, but every now and then they do require a bit of care and attention. Fuel tanks are particularly vulnerable to corrosion and contaminants in the fuel, and if left unattended this could lead to problems in your truck's fuel delivery system as well as in engine performance.

Proper use and maintenance of the fuel tank is really not that complicated, and leans more on common sense than specialized tools. To help you get started, here are some tips you can follow:

  • Don't let the fuel tank come close to empty.

Aside from potentially finding yourself out of gas on the side of the highway in the middle of nowhere, low fuel levels may also cause the inside of the tank to rapidly heat up and damage the electronic sensors inside it. Gasoline and diesel actually make good heat absorbers, and keeping the fuel levels high will also maintain the temperature inside the tank at a safe level.

  • Don't let fuel sit for a long period of time.

If your truck will be idle for a long period of time, you may want to consider draining the fuel out of the tank. This is because particulates from the fuel might settle down at the bottom of the tank, making it harder to remove by the fuel filter. In addition, stagnant fuel may also encourage the growth of algae inside the tank, clogging up the fuel lines. You can siphon the tank onto a gas can or a similarly container, and refill it once you are going to start driving your truck again.

  • Use only clean fuel.

Not sure if the cheap gas they're offering at the roadside? It's better to be safe than sorry and just find a reputable gas station. While less expensive, low quality gas may not be refined properly and might contain harmful particulates that can clog up the pipes and damage both the tank and the engine. And once the fuel tank is contaminated, you will need to have it flushed or even replaced in order to completely remove the contamination.

  • Tips on Replacing the Ford F-250 Super Duty Fuel Tank

    Installing a new gas tank in the Ford F-250 Super Duty is a task that doesn't happen very often. But if the tank has developed a leak, has been punctured or damaged, it will have to be replaced as soon as possible to prevent fuel from leaking out or being contaminated by dirt and rust.

    Most auto service centers are up to the task of removing and installing Ford F-250 Super Duty fuel tanks, although it is possible to do them yourself at your garage. If you intend on replacing the fuel tank in your Ford F-250 Super Duty, here are some tips that might help you out.

    Tip #1: Drain the tank.

    Both gasoline and diesel are highly flammable compounds whose vapors alone can start a fire, so make sure that the tank is empty before starting. You can either choose to siphon the gas through the filler hose, or detach the rubber fuel line at the end connecting to the gas tank and the fuel drain out. If your tank has a drain cock at the bottom, you can loosen the valve at the end and the fuel will pour out.

    Store the leftover fuel in a gas can or a similar inert, non-flammable container, although we do not recommend reusing the gas in your truck as it might already be contaminated with dirt and rust particles from your old tank.

    Tip #2: Disconnect the fuel lines.

    Aside from a pair of metal straps, the fuel tank is also held in place by several fuel lines that you will need to disconnect. Take a camera with you and snap a picture of the tank before you take it apart. This way, you'll be able to identify which fuel line goes where when mounting the new tank.

    Tip #3: Use penetrating oil on those hard to remove straps.

    The bolts that hold the fuel tank straps in place tend to accumulate road gunk and rust over time, so removing them might require a bit of an effort. However, if the bolts are especially uncooperative, you can try spraying the bolts first with penetrating oil and let it soak for several minutes. The oil should break the dirt and rust enough for you to loosen them with the wrench.
