Fuel Lock Sizes
The Fuel Lock comes in four different sizes, 2½”3”, 3½”, 4” and 4½”. To determine the right size for your fuel tank measure the width of the filler neck on your fuel tank.
Please Note: In order to be functional, The Fuel Lock requires space around the cap to be clear. For proper installation the minimum required clearance around fairings is 7”. It will not function on trucks that are fitted with this step.
