Chris Riley is now joint top Super League try scorer with Pat Richards
Challenge Cup holders Warrington will return to Wembley next weekend on the back of a three-game winning run after twice coming from behind to beat Hull.
Winger Chris Riley scored twice before the break to cancel out tries by Tom Briscoe and Epalahame Lauaki.
But Wolves added four more after the restart from Jon Clarke, Ben Westwood, Adrian Morley and Richie Myler.
And that was enough to remove Hull from fourth place in Super League, thanks to Leeds' 52-6 thumping of Catalans.
But Hull still have a chance of going back above Leeds on the final Super League weekend of the season when the pair meet in a 'winner-takes-fourth' clash at the KC Stadium in a fortnight's time (3 September, 2000 BST).
It was all square at the break after Riley twice helped the Wolves come from behind.
He pounced in the 21st and 40th minutes to take his Super League tally for the season to 25, taking him level with this season's top try scorer, Wigan's Pat Richards.
But the Wolves eventually ran away with it after the break as Hull paid a heavy price for the sin-binning of Danny Tickle.
The second rower was yellow carded after 54 minutes for a cynical foul and the Wolves punished his error by scoring two converted tries by Clarke and Westwood.
I thought Ben Westwood was terrific. He plays very similar to that very often but he was absolutely a stand-out
Warrington coach Tony Smith
Hull responded when Lee Radford got away with a lucky bounce off his knee to run and score under the posts, to make it 24-18.
But Warrington hit back immediately with two more tries by skipper Morley and young stand-off Myler.
Wolves boss Tony Smith opted to rest influential stand-off Lee Briers and former Hull prop forward Garreth Carvell a week out from their Wembley showdown with Leeds.
But it was still a strong-looking side as they sought the points to keep alive their hopes of a second-placed finish.
Hull dominated the opening exchanges and it was no surprise when they went ahead after nine minutes.
Riley shot out of the defensive line to allow Hull's England international Tom Briscoe to go past him and touch down at the corner despite the attention of two other defenders.
Tickle's touchline conversion went in off an upright to give the Black and Whites a 6-0 lead. But Warrington were level midway through the half when Louis Anderson's accurate pass found Riley in space.
Westwood fired the first of his six successful kicks out of six at goal - a welcome sign ahead of next week for the Wolves, whose kicking his certainly not been in Kevin Sinfield's class this season.
Hull full-back Craig Hall then had a try disallowed by video referee Ben Thaler for an obstruction by team-mate Tickle. But their pressure paid off four minutes from the break when loose forward Craig Fitzgibbon offloaded from the tackle to get substitute Lauaki over.
Tickle's second goal restored Hull's six-point advantage but it was all square once more when Riley took a scoring return pass from centre partner Atkins.
After centre Matt King had a try chalked off, it took until the visitors were down to 12 men before Warrington went ahead for the first time.
Tickle was sin-binned for holding down Michael Monaghan in the tackle and the Wolves made the extra man pay.
They ran the ball on the last tackle, Monaghan handling twice before hooker Clarke finished off the sparkling move.
Hull were still a man down when Westwood snapped up a Paul Wood offload to power over for a try, getting away with a double movement.
The visitors pulled a try back on Tickle's return from the bin, Radford touching down after clumsily hacking forward a pass from Sam Moa.
But, from the restart, Morley cashed in on loose handling to force his way over from close range for his third try of the season and Myler snapped up Clarke's pinpoint pass to race away for a cake-icing sixth try.
Warrington coach Tony Smith:
"I thought in the first half we were okay, that's all. We weren't bad but I didn't think we were great.
"We had to raise the bar for ourselves in the second half. We changed some tactics and kicked the ball a bit earlier. We upped the pace a bit and controlled the game. I was pretty happy with the way the second half went.
"I thought Ben Westwood was terrific. He plays very similar to that very often but he was absolutely a stand-out tonight."
Hull FC coach Richard Agar:
"In the first half I thought we played with a great intensity. The rotation of our big fellas helped us and we played some good rugby.
"The turning point - and it was probably the correct decision - was the sin-binning [of Danny Tickle]. It's very difficult to defend against a quality team with 12 men.
"Not only did they post two tries but they burnt us up energy wise as well."
