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.
