Arsenal, bidding to become the first side since the 19th Century to win the FA Cup three years in a row, dominated the game but could not find a way past Hull goalkeeper Eldin Jakupovic, who made several fine saves.
With Arsenal pushing for the Premier League title and at home to Spanish giants Barcelona in the last 16 of the Champions League on Tuesday, the prospect of another game was far from ideal.
"No not especially good news but Hull defended very well," Arsenal manager Arsene Wenger told BT Sport when asked about a replay at north-east side's Hull KC Stadium.
"As long as they (Hull) did not concede, they maintained with how they played. We had 20 shots, 70 percent possession but no goals," explained Wenger, who earlier this week refused to back calls, supported by Hull boss Steve Bruce, for FA Cup replays to be scrapped.
Wenger, whose side beat Hull in the 2014 FA Cup final and knocked them out in the third round last season, added: "I think FA Cup replays are a peculiarity of the English rules and you have to respect that.
"The Hull goalkeeper was outstanding and kept them in the game."
Bruce too praised Jakupovic, one of 10 changes he made to his starting side.
"It's been frustrating for Eldin, he's never had a crack at playing regularly, but he's come in and made some great saves," said Bruce.
"I don't know when we're going to play (the replay). That's added to the fixture pile-up we've got."

But interim Chelsea manager Guus Hiddink was wary of a backlash from City, who come into the match on the back of successive defeats by Premier league title rivals Leicester and Tottenham.
"A big team always reacts. We are warned," said Hiddink, who will be without injured captain John Terry.
