Ford F-250 Fuel Tank

How to Make the Ford F-250 Fuel Tank Last Longer

The gas tank is one of the last parts you'll ever have to worry about in the Ford F-250, but it does need a bit of maintenance from time to time. Thankfully, maintaining the Ford F-250 fuel tank leans more towards the preventive side, particularly in how the tank is refilled. Here are some tips on how to take care of your Ford F-250 fuel tank:

  • Don't let the tank run empty.

Arguably, the simplest way you can keep the fuel tank in top condition is to keep it at least half-full with gas. While not being consumed by the engine, gasoline absorbs heat generated by the tank's fuel pump and from the engine. And if the tank's fuel levels fall dangerously low, the temperature in the tank rises accordingly. This added heat will put the tank, the fuel pump, and other fuel system components under stress and shorten their service lives.

  • Don't use a dirty or rusted fuel nozzle when refilling.

Dirt, grease, or rust particles on the nozzle can transfer onto the fuel door and into the tank, potentially contaminating the gas stored inside. So if the nozzle appears dirty or corroded, switch to another pump or, if need be, drive to another gas station.

  • If the truck will be idle for long periods of time, drain the gas from the tank.

If you won't be using your F-250 truck for two weeks or more, it may be best to drain off any remaining fuel from the tank. Automotive fuel tends to “sour” over time, which in turn can lead to corrosion and clogging in the tank as well as a variety of engine-related problems. Diesel in particular has it worse, as stagnant diesel fuel can harbor the growth of algae which turns the inside of the tank into a gooey mess.

  • Change the fuel filter regularly.

Ford recommends changing the fuel filter once every 15,000 miles, although you may need to do it earlier if you suspect the tank is tainted with contaminants. Ford fuel filters are highly efficient in catching microscopic particulates from the fuel, but over time these will build up and prevent the fuel from flowing freely to the engine.

  • A Few Helpful Tips in Replacing the Ford F-250 Fuel Tank

    The Ford F-250 may have packed in some new bells and whistles over the years, but one thing that will stay the same is the fuel tank under the chassis. A mainstay in any gas-operated motor vehicle, the fuel tank has the simple yet critical task of storing Ford F-250's fuel, so once it gets rusted or has sprung a leak, it needs to be replaced as soon as possible. Thankfully, a replacement Ford F-250 fuel tank is not that hard to find nowadays, and is just as easy to install on your own. If you intend to change your Ford F-250 fuel tank all by yourself, here are some key tips to remember:

    Tip #1: Empty the fuel tank and lines.

    Draining is especially important if the tank is fouled by rust or other contaminants, as the gas may carry the particles through the system and contaminate the new tank later on. The Ford F-250 has a drain plug on the tank for this purpose, so all you have to do is to loosen the plug and let the gas drain into a large oil pan or bucket. Make sure to store or, in the case of a fouled tank, dispose of the gas accordingly.

    Tip #2: Don't touch the tank while the engine is still hot.

    Anything that's connected to the engine will absorb some of its heat, and that includes the fuel tank. So to prevent burns, allow the engine to cool down to the point where it is cold enough to the touch. Also, even if the tank has cooled down, we still recommend wearing some insulated gloves as an extra precaution.

    Tip #3: Snap a photo of the fuel tank before you take out the fuel lines.

    Taking a picture of your car's fuel tank may seem like an odd (or vain) thing to do, but you'll find it much easier to determine which fuel line goes where if you have a photo of it before lines were detached.

    Tip #4: Make sure the contact surfaces between the tank and the underside of the vehicle is clean.

    Dirt that's trapped in between will cause rust to form, which is a bad thing to the tank's steel body. If the car's underside is rusted, damaged, or worn, have it patched up first before mounting the tank.
