Tries: Hall, Briscoe 4, Turner Goals: Whiting 3
Keith Senior and Ryan Hall bagged two tries each as Leeds earned their most impressive win so far this season.
Centre Senior struck first inside five minutes, winger Hall adding his two as the Rhinos edged 16-10 up at the break.
But, after being pegged back by the third of Tom Briscoe's four tries, Leeds added five more in a stunning 21-minute spell after the break.
Ali Lauitiiti, Senior, Rob Burrow, Jamie Jones-Buchanan and Danny McGuire all crossed before Hull's late rally.
Centre Craig Hall, winger Briscoe and stand-off Jordan Turner all scored inside the last six minutes as Hull salvaged some pride from this dress rehearsal for next Saturday's Challenge Cup fourth round tie at the KC Stadium.
Champions Leeds drew first blood when a long cut-out pass from Burrow found Brent Webb and, although the move looked to have come to grief, the Rhinos full-back came up with a superb offload for Senior to race over in the corner.
Kevin Sinfield nailed a tricky-looking conversion before making the initial break for Leeds' second on 18 minutes.
The Rhinos captain found support in Burrow, who checked in the middle of the park before finding eventual try scorer Hall, who shrugged off Richard Whiting on his way to the line.
Sinfield slotted the conversion before a magnificent third on 25 minutes, McGuire and Burrow neatly interchanging passes to set up Senior, who unselfishly popped the ball left for Hall to dive in.
After Sinfield had missed the goal, from 16-0 down, the Black and Whites hit back on 29 minutes with a score completely against the run of play.
Kirk Yeaman was twice the provider as Briscoe crossed twice inside four minutes. And, serving up one of the Super League's quicker trebles, he completed his hat-trick just five minutes after the interval thanks to Jordan Tansey's well-timed ball.
Having been hauled back to 16-14, Leeds stemmed the flow when, from Senior's long pass, Lauitiiti bulldozed over to stretch the home side clear again four minutes later.
Senior then got his second of the afternoon, slicing through before swapping passes with Webb in support. And Hall raced clear on the left to feed Burrow for another before Jones-Buchanan also barged his way over.
The visitors did cross for those three late consolations but improving Leeds had long since sealed their second league win on the trot.
Leeds coach Brian McClennan said:
"I think both squads, when they review this game tomorrow, will find it hard to work it all out.
"We'll review the game and then start our preparations [ahead of the two sides meeting again in the Challenge Cup next week].
"I don't know what to expect, we'll concentrate on ourselves and prepare thoroughly."
Hull coach Richard Agar said:
"To come here and score as many points as we did, and to create even more chances, should be enough to win the game.
"But defensively if you miss your one-on-ones and let them offload like we did then you pay a heavy price, especially against a team with so much pace.
"In the first half we let them start with too much tempo. We fought our way back well and looked a threat with field position, but defensively we looked a bit short of intensity."
