After Saturday's poor performance at Steyning manager Paul Daubeney was looking for the right reaction to keep United's promotion hopes on track and he got it
His team selection was not helped by the withdrawal of the county's leading scorer Liam Baitup with the striker feeling unwell, Shaun Lee's broken bone in his ankle and keeper Adam Sargent unavailable.
Lee Daubeney came in between the sticks for his first game since March 2012 while Jamie Bunn and Nick Barden returned to the starting lineup.
There was also a place on the bench for Danny Simmonds after his return from injury
United didn't get the start they were looking for when inside the first minute a speculative lob from 40 yards from Jordan Woodley was helped into the top corner of the goal by the back peddling Daubeney, but gradually United found some control of the game and Simon Catt and Jamie Bunn were particularly prominent.
On 12 minutes the scores were level when Catt fed Bunn who's deep cross was returned by Barden, where Bunn headed in at the far post.
Three minutes later United were ahead, a cross from Filsell caused hesitancy between keeper and defender and Nick Barden nipped in to prod the ball home.
Bexhill now upped their game and with Woodley pulling the strings started to look dangerous.
Josh Elliott-Noye had two efforts from a corner blocked on the line, Bryce Masters had a goal ruled out for offside and Will Dunstall shot wide after a long throw from Steve Morris had caused problems.
It wasn't all one way though and Peter Cooper crossed invitingly but Bunn shot over and Calum Sherriff volleyed over the bar from a corner.
On 39 minutes Dunstall received a yellow card for a late challenge on Filsell that ended his game as he was replaced by Mark Goodwin, with Bunn switching to full back.
As the second half started the feeling was that there were more goals to come and Catt struck a powerful shot just wide, but it was Bexhill that began to press and they were causing most problems with the long throw deep into the United penalty area.
From one of these Dunstall missed from 6 yards and former EUAFC midfielder Tom Morton brought a superb one handed save from Daubeney but in general United's defence with skipper Pete Featherstone outstanding, were coping well.
Bexhill substitute Paul Rogers was booked for dissent and Garman for comments made to the assistant.
At the other end United had two efforts from a corner blocked on the line, Goodwin headed over a good cross from Cooper and Cooper himself struck the foot of the post with a shot from the edge of the box. As added time approached there was more trouble for the officials after Rogers had bundled Featherstone over but the free-kick was somehow given Bexhill's way. Justice was done however when the header from the kick hit the bar and was bundle over the line only to be ruled out for off-side.
Players then surrounded the referee and his assistant with another former EUAFC player Steve Morris receiving his marching orders along with a member of the Bexhill management after running up the touchline to vent his feelings towards the officials took himself to the changing room.
After close to ten minutes added time United remained victorious and their promotion push is back on track just in time for a trip to second placed Littlehampton Town this Saturday
