That's a very open-ended question. A bit more detail of what you're doing, or at the very least mentioning what year and model truck you're working on would generate more accurate answers. Ford made gas tanks specificially for every model they ever built. And being one of the most popular vehicles ever made, replacement parts are readily available so you can get the correct part easily. Beyond that, nearly any tank can be made to fit, it just depends on how hard you want to work to make it fit.
Assuming this is an "in cab" 18 gal fuel tank, 1961 to 1964, 100 through 700 series Ford truck is an exact fit.
