Vintage Flush Mount Boat Fuel Cap 3.5" FUEL Stamped Marine Alloy 495g Heavy

Weight: 495g (about 17.5 oz—hefty solid cast construction, not lightweight junk). Stamped "FUEL" on the lid for easy ID, and it's built tough with a knurled twist-off cap, three mounting holes on the flange, and intact internal threading for a secure fit.
