2-Ear Pinch Clamp, Stainless, 0.866 - 0.984 Inch Clamping Range, 0.394 Inch Width

These clamps are especially suited for industrial use, including equipment that vibrates a lot. They’re often used on lines carrying fluids, so it should be a good fit for a fuel line, giving you a positive, tamper-proof seal.

For a hose sitting right around 15/16 inch, you're in good shape. The clamping range runs from 0.866 to 0.984 inch, so anything in that neighborhood falls right in the middle of what this clamp is built for. One thing worth knowing though: if you close both ears completely and there's no resistance, the clamp is probably too big and you'd want to drop down a size. A properly fitted clamp should still have a little spring tension left in it after installation.
