The visitors were playing some nice stuff as they moved the ball around at pace and they grabbed an equaliser with 19 minutes through the impressive Ritchie Partridge, the ex-Liverpool man converting a cross from the left supplied by City debutant Paul McManus. Carlisle re-took the lead eight minutes before the interval when Marc Bridge-Wilkinson jinked in from the right and fired an unstoppable left-footed drive low into the far bottom corner.
The game was effectively sealed by the Cumbrians in two minutes around the 53 minute mark. Firstly Gall scoring his second of the night with a tap-in after Danny Livesey had seen his header from a Bridge-Wilkinson corner well saved by Danby. Then just over sixty seconds later Graham latched on to a perfect Bridge-Wilkinson ball over the top to slot home comfortably past the Chester keeper for his ninth goal of the season that put Carlisle 4-1 ahead.
The visitors kept battling though and they made it 4-2 when substitute Chris Holroyd, who had only been on the field a matter of seconds, headed powerfully home past Keiren Westwood in the United goal from a pinpoint cross in by Paul Rutherford. Further chances came and went for both sides but neither team troubled the scorers any more as the Cumbrians progressed safely through to the last eight of the Northern Section.
