Its silicone (liquid) fill reduces pointer flutter from engine vibration, while the stainless steel case and brass internals resist corrosion from fuel system exposure. An easy-access vent plug lets trapped air escape so you get accurate measurements every time.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Marshall gauge keep readings steady under vibration?\u003c\/h3\u003e\n\n\u003cp\u003eThe gauge is filled with silicone liquid to dampen internal movement and minimize pointer bounce caused by engine and road vibration.
