The first game ended in a 2-2 draw on Saturday and the teams will return to Mill Road on Tuesday night with Gullivers still in the hands of Sidley Cricket Club.
Marc Munday put Sidley ahead with his first goal for the club, but two goals in quick succession - the first from a hotly disputed penalty - turned the game on its head. Scott McDonald levelled for the Blues in the second half.
Sidley remain top of the fledgling Sussex County League Division One table because Rye United could only manage a 2-2 draw away to Worthing United.
Rye were a goal behind at half time and their deficit was doubled around the hour mark, but two goals from substitute Matt Maclean preserved their unbeaten start. Worthing had a player sent-off late on.
Westfield romped to a 6-0 victory at home to Midhurst & Easebourne in Division Two. Roberto Martelini and Joe Barham put them two-up at half time, and further goals from Barham, Peter Baker, Sam Willett and Martelini completed the rout.
Bexhill United made it back-to-back wins in the same division with a 2-1 success at Steyning Town. After falling behind early on, Andy Garman equalised before the break and Dan Hill scored a deserved winner in the second half.
Little Common picked up their first point in Division Two via a 2-2 draw at Loxwood. Jamie Crone and Chas Lister were on target for a below strength Common side.
