Guiseley snatched their first win of the season from the jaws of defeat with two goals in the last five minutes to deny managerless Torquay victory and leave them bottom of the table.
Having battered the visitors goal for the first half hour and taken the lead through Jake Lawlor, the Lions somehow found themselves going into the break 2-1 down as Sean McGinty and Ruairi Keating stunned the home supporters with two goals in as many minutes before the break.
Then after Torquay had dominated much of the second period substitutes Kevan Hurst and Lee Molyneux produced the goods in a devastating last five minutes to leave United still searching for their first win of the season.
The Lions began at a blistering pace with Alex Purver firing over early on and eventually took the lead following a series of corners the last of which from John Rooney was headed against the bar by Danny Lowe with Jake Lawlor on hand to convert the rebound at the far post on 13 minutes.
The pressure continued unabated and Rooney was denied by Ryan Clarke, Connor Brown was also unfortunate to see his fierce drive come back off the foot of the post with Clarke beaten.
The unmarked McGinty then headed home from a corner to square matters on 39 minutes and the visitors then took the lead with Keating finished of a quick one-two with Jake Gosling to beat Joe Green a minute later.
Guiseley replied with another series of corners with Lawlor’s header blocked by Clarke and Reece Thompson’s header coming back off the bar.
United began the second half on the front foot as the Lions had Green to thank for keeping them in the game as he denied John-Paul Pitman, Jamie Reed and Jake Gosling in quick succession.
Manager Adam Lockwood sent on Frank Mulhern, Hurst and Molyneux which proved crucial as the latter two grabbed an unlikely win.
Will Hatfield and Rooney had shots blocked but when Purver’s free kick saw a bout of head tennis in the area the ball eventually fell to Hurst who smashed it home at the near post on 86 minutes.
With their tails up and five added minutes to play the Lions mounted an all-out assault that led to a massive melee in the six yard box with the ball being cleared off the line twice before Molyneux got the final touch as the ball went in off Keating in the final minutes to complete an unlikely comeback.
