With not much to choose between the two sides during the first game on Sunday, tonight's game promises to be a mouth-watering occasion.
Mikey Lloyd scored Haven's all important goal two days ago but The Deres showed how dangerous they can be when they worked a very good equaliser.
Peacehaven fans love a cup game and tonight's game looks finely poised.
If required extra time will come into play and if that doesn't generate a winner, there will be a penalty shootout.
Because it's a cup match the game kicks-off at 7.30pm. If you're a season ticket holder you will have to pay the normal entry price for this game as FA Cup games are not covered by season tickets.
Entry is £7 for adults and £5 for for over 65s. Under 18s get in for free. The clubhouse and snack bar will both be open.
