Yep. Happened to me in my previous pickup truck. If you have an idea what kind of gas mileage you get, you can use the trip odometer to ensure you don't run out of fuel before you can get the sending unit replaced. Just remember to reset the trip odometer every time you fill up, and plan to fill up when you're about 100 miles shy of your minimum range, to allow a reserve just in case.
