Standard Ignition Vapor Canister P/N:CP3240
Capture fuel vapors and keep your evaporative emission (EVAP) system sealed with the Standard Ignition Vapor Canister CP1022. The charcoal-filled canister stores fuel vapor drawn from the fuel tank and holds it until the purge system routes it to the engine intake to be burned — helping manage tank pressure and control raw fuel-vapor escape. It drops in as a direct-fit OE replacement across a large range of GM cars and trucks, including the 1973-1975 Buick Apollo, 1972-1977 Buick LeSabre, 1971-1979 Cadillac DeVille, 1975-1977 Chevrolet Caprice, 1986-1993 Chevrolet S10 and 1975-1977 GMC C15. This one MPN spans 163 applications — see the Buyer's Guide tab for the full list and the specific engines.
If a saturated or cracked canister is the cause of a fuel odor or an EVAP-related check engine light, this replaces it; diagnose the system first, as other components can trigger the same codes.
