Gauge lines carry pressure or fluid from the engine to a mechanical gauge, so readings like boost, oil or fuel pressure reach the dashboard.
When choosing one, match the line to the gauge type and the fluid it will carry. Check that the fittings suit your gauge and sender port, and allow enough length for clean routing away from hot or moving parts. Then pick your vehicle to see what fits.
