Having beaten Crystal Palace on Saturday, United fielded an unchanged side for the visit of Leicester City and Neil Warnock's side got off to the perfect start.
Jeff Schlupp was guilty of bringing Sam Byram down in the box and Luciano Becchio stepped up to smash the penalty past Kasper Schmeichel. It was another good start by Leeds and some more good play ended when an offside flag was raised to deny a decent opportunity.
The 11th minute brought about chants of "Gary Speed" from the crowd with the game falling on the first anniversary of the death of the club's former title winning hero.
Leicester's first opportunity came when Richie De Laet fired a shot at Paddy Kenny from a tight angle, but United looked by far the sharper of the two sides with Jerome Thomas again causing problems down the left.
United fashioned out another great chance before half-time when Becchio turned provider with a left-wing cross and Paul Green was denied by a superb save by Schmeichel. The visitors were a threat, though, when they cam forward and Martyn Waghorn sent a fizzing volley across the face of goal.
Along with Becchio and the lively El-Hadji Diouf, Thomas was a constant nuisance for Leeds, and there were further shouts for a penalty when the loan man burst into the box before being denied by a good challenge from De Laet.
It had been another good first half display by Leeds and when Leicester threatened at the start of the second half, Lee Peltier made a vital block after Waghorn made a good run on goal.
But United continued to look to strong and Thomas curled a shot wide after some great individual work.
Leicester made a double change before the hour and one of those substitutes, Anthony Knockaert, forced Paddy Kenny into making his first real save of the game when he had to get down low to his right to push a shot away.
Michael Brown replaced Thomas shortly after the hour, and the Leeds substitute came within a whisker of furthering the advantage when he drilled a shot wide after Leicester failed to clear their lines.
At the other end, Mark Futacs sent a shot just wide of the upright after some good play by the hosts and Green did well to clear under pressure from Lloyd Dyer.
United had the ball in the net on 84 minutes, but an offside flag ruled Becchio's effort out after the striker had rounded Schmeichel and rolled his finish home. And with three minutes remaining David Norris had an opportunity to round off a great individual performance with a speculative goal, but his first time strike from distance was over the top.
Four minutes were added on, and in the third of those Kenny was adjudged to have tipped a long ball forward from Schmeichel over the bar. The visiting keeper came forward for the resultant corner, but United defended in numbers and Tom Lees made a great block in the final action of the game.
