Hull took their winning sequence to 13 games as Richard Horne equalled a 92-year-old club try-scoring record, but Warrington threatened to upset their progress .
It took Hull six minutes to score. Paul Cooke put through a well-judged kick and the young loose-forward Danny Washbrook timed his run for the touchdown. Their second try, 10 minutes later, came from a Warrington mistake as Stuart Reardon threw a wild pass for Gareth Raynor to intercept and run 80 metres to score.
When Cooke kicked across field for Motu Tony to catch and ground the ball just before the deadball line it seemed that Hull, for whom Cooke kicked all three conversions, were taking complete control. To Warrington's credit, however, they came back with two tries in five minutes.
The first came when Lee Briers kicked towards the corner, Brent Grose knocked the ball down and Toa Kohe-Love seized the loose ball. The second came when Briers sent Martin Gleeson striding through a gap to find Logan Swann in support for another converted try to cut the margin to six points.
That would have been satisfactory for the Wolves at the break, but on the stroke of half-time Richard Horne scored in an 11th consecutive game, thanks to his younger brother, Graeme, who ran on to Shaun Briscoe's kick. He was over the line before he passed to his sibling, with Cooke's fourth conversion stretching the lead to 12.
That try was awarded by the video referee on the new benefit of the doubt ruling, and Warrington would have been right back in contention but for Raynor's magnificent tackle on Henry Fa'afali.
Hull's teenage half-back, Tommy Lee, then threw a pass which was intercepted by Grose for a try that Warrington deserved. To make up for it, Lee latched on to an inside ball from Nathan Blacklock to get over the Warrington line and make the game safe.
Shaun Briscoe's effort from Ewan Dowes' break sealed it, despite a late Wolves score from Richie Barnett.
