Liverpool, who face Real Madrid in the Champions League on Wednesday, have now drawn six home matches in the league this season and their chances of a first league title since 1990 appear to be fading fast.
With 12 games remaining they are in second place with 55 points to Manchester United's 62 after the champions clocked up a 10th consecutive league victory at home to Blackburn Rovers on Saturday. Third-placed Chelsea have 52 points.
"When you are playing catch-up you need to win so we are disappointed," Benitez, who refused to concede that his side were now too far behind United, told Sky Sports.
"We lost two points but we still have to play at United so we will see."
Albert Riera wasted Liverpool's only real chance in the opening half when he dragged a shot wide and seven minutes after the break Anfield was silenced by Welsh striker Bellamy who Benitez felt was surplus to requirements in 2007.
Kuyt equalised after 78 minutes when he stabbed in Fernando Torres's scuffed attempt and Liverpool could have snatched an unlikely victory through Yossi Benayoun.
