Gloucester went behind in the first half but fought back valiantly late on in the game to steal all three points.
The visitors took the lead after 19 minutes before two second half goals rounded off a fantastic comeback for the Tigers.
Gloucester did have two injuries in the first half with Josh Thomas and Fabien Robert limping off.
Gloucester move up the table to 18th and are now 10 points above the drop zone with as many as three games in hand on the teams above.
“What we have got now is belief and I think this little run we’ve had has given them a fantastic spirit of ‘we won’t be beat’ and they showed that today,” said Gloucester’s assistant manager George Foster.
Farsley Celtic took the lead before the 20-minute mark when their number 9 Dave Syes skipped past his defender to rifle the ball into the roof of the net from close range.
“We felt that they were controlling the game, so the manager had to do something about it and he did with his formation change,” said Foster
“We’re part time at the moment, the manager only has them on a Tuesday and Thursday night for an hour and a half and he has to get all that work into them.”
Gloucester came back into the game with just over 20 minutes to go, a fantastic cross drifted into the box by substitute Taylor Allen that met the head of Mathew McClure at the back post who glanced it home.
“I’ve got up and just slightly glanced it into the far corner but It was a great cross from Taylor and a good assist,” said goal scorer McClure after the game.
It wasn’t until the 92nd minute when Gloucester snatched a winner, Marlon Jackson stepped past his defender and cut the ball back to Bernard Mensah who curled the ball home from just inside the box.
This was Mensah’s second goal in two days after scoring away at Kettering Town on Saturday afternoon in a 1-1 draw.
After storms Ciara, Dennis and Jorge; the Tigers had to go almost a month without playing football but George Foster thinks that may have benefited the side:
“It’s given James [Rowe] more time on the training ground with them and it’s given the players more time to gel together.”
Gloucester are at home again next Saturday as they welcome Blyth Spartans to the Jubilee Stadium.
“They’re all big games at this part of the season but as long as we go out there and work as hard as we possibly can, then whatever the result is we’ll come off and be proud that we’ve done that,” said McClure.
