United's fans will be in the Waterworks End on the advice of Cumbria Police, who recommended that Leeds receive the lowest allocation possible under Football League rules in an attempt to avoid a repeat of crowd problems seen during the 3-1 defeat at Carlisle earlier in the season.
Leeds received 3,249 tickets for their trip to Brunton Park on November 3 and helped to create Carlisle's biggest home gate for three decades.
The Football League's regulations stipulate that visiting clubs must be offered at least 10% of a stadium's capacity or 2,000 tickets, whichever is lower, and Brunton Park is capable of holding around 16,600 fans.
Leeds have provided Carlisle with exactly 2,000 seats for the first leg at Elland Road next Monday.
