Match Summary
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for his side not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the post for the confident home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had two days less to prepare, Cunha levelled three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of injury and national team commitments.
Not that Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends Leeds' unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's options.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding clear improvement.
The job is not done yet but gradually, the team are getting closer to achieving their survival.
