They were behind after six minutes of their last-16 clash at the Grande Stade Tangier but Gueye scored two goals before halftime and 17-year-old Ibrahima Mbaye added a third 13 minutes from the end.
Senegal will now meet either Mali or Tunisia, who were playing later on Saturday in Casablanca, in the last eight on Friday. Senegal, the 2021 Cup of Nations winners, are the second-ranked team in Africa and, despite conceding early, showed their quality and strength to win in comfortable fashion.
Sudan took a surprise lead with a classy goal as the Australian-based Aamir Abdallah, who plays in the state league in Victoria, cut inside the much vaunted Senegal defence and curled a left-footed effort wide of Edouard Mendy.
It was a shock setback for the highly fancied Senegal but they quickly assumed control of the game, dominating possession and fighting their way back to lead at the break.
Nicolas Jackson had a point-blank effort expertly stopped by Sudan goalkeeper Mongeel El Neel but a minute later Senegal were level when Mane pinched possession in midfield from Abuaagla Abdallah and fed Gueye, who stuck his effort into the corner of the goal.
