The gas tank size of a 2014 Ford E350 is 33 gallons, regardless of the engine type. 
It’s important to know your tank size when you pull up to the gas pump so you’re prepared for how much gas you’ll need to purchase. This information is in the owner’s manual, but if you don’t have it on hand, you’ll need to find the information somewhere else.

How big is the gas tank on a 2014 Ford E350?

As a full-sized van, the 2014 Ford E350 needs a gas tank that can keep up with its demand for fuel. The gas tank is the same size no matter what trim level or configuration you choose.
The 2014 Ford E350’s gas tank is 33 gallons. It comes with either a 5.4-L V8 or a 6.8-L V10 engine. Both engines have the same gas tank.

How to check your 2014 Ford E350’s gas tank size

If you’d rather check the capacity for yourself, there are a couple of different ways you can go about it. Here are some techniques for measuring the gas tank size.

Measure the gas tank

It’s possible to measure the volume of the gas tank on your own. You’ll need a measuring tape and a calculator to measure the width, length, and height of the gas tank. Multiply these numbers together, and divide this sum by 231, or, the number of cubic inches in a gallon.

Check your owner’s manual

Refer to your owner’s manual for concrete information on the gas tank size. You’ll see a phrase like “fuel tank capacity” or similar to direct you to the information you need.

Drive till empty, then fill it up

Another, albeit risky, way to check the gas tank size is to drive until the fuel gauge hits “E” and then fill up the tank. This is the least precise way of measuring the gas tank, but you’ll get a general idea of the tank size. Be sure you don’t run out of gas when employing this method.

How to save on fuel costs in a Ford E350

The gas mileage on a 2014 Ford E350 isn’t impressive, but that’s to be expected with a full-size van. The mileage is 12 mpg city and 16 mpg highway or 13 mpg combined.
Driving a vehicle this poor on gas mileage surely motivates you to find ways to save at the pump. Follow these tips to save on gas:
  • Maintain your vehicle regularly. If you let wear and tear carry on for too long, it’ll start to wear on your fuel economy.
  • Drive safely. Don’t accelerate quickly and drive a little slower to save on gas.
  • Don’t let your engine idle, especially in cold weather. It might be tempting to let your engine run for a few minutes to warm up your car on a cold day, but idling the engine burns gas and lowers your fuel economy.
