A fuel vapor purge system may include a turbocharger including a turbine disposed in an exhaust line, and a compressor; a canister connected to a fuel tank through a vapor line; a fuel pressure detector configured for detecting pressure in the fuel tank; a canister closing valve selectively closing an atmospheric path provided in the canister; a purge control solenoid valve disposed in a main purge line connected to the canister and selectively closing fuel vapor collected at the canister; a first check valve disposed in a first purge line and preventing the fuel vapor flowing along the firstpurge line from flowing reversely; a second check valve disposed in a second purge line preventing the fuel vapor flowing along the second purge line from flowing reversely; a differential pressure generating valve disposed in the intake line, and generating negative pressure; and an intake pressure sensor disposed in the intake line between the differential pressure generating valve and the compressor.
