Roewe 750 and MG MG7 Vacuum Carbon Canister Solenoid Valve, OEM 1997279/1997252/1997312 Universal Replacement

Vacuum carbon canister solenoid valve for Roewe 750 and MG7, universal replacements with original numbers 1997279, 1997252, 1997312. This valve controls the fuel vapor recycling path from the charcoal canister to the engine combustion chamber, reducing emissions waste and preventing tank collapse. When warmed engine idles erratically, start is hard, or when fueling there is suction near the filler cap, the valve may age out. Replacing restores fuel system pressure balance, reduces fuel consumption, and improves drive feel. Install with sealed hose connections; no extra adjustments needed.
