Dave Edwards' 88th-minute header finally saw off a spirited Leeds fight back and claimed a priceless 4-3 victory, to propel Wolverhampton Wanderers back into the play-off places.
With just nine points separating the top eight teams in the Sky Bet Championship, the play-off make up is sure to change many more times over the remaining five games, but Jackett feels his side have the momentum to keep going.
Wolves have now won their last four games in a row and have lost just once in 10 games, and Jackett believes his team can continue to get better, and in doing so the Molineux crowd can help to get them over the line.
Speaking to BBC Sport, Jackett said: "We can sense something happening and we just need to focus on getting our game right. If we keep improving and show a hunger to play good football, the crowd will follow us.
"We feel that we've got a lot of goals in our team and it's tight between all of the sides. We're just pleased to be in and around it but we need to concentrate and finish the season off strongly."
Goals from Nouha Dicko (2) and Benik Afobe had given Wolves a 3-1 lead in response to Charlie Taylor opening the scoring for Leeds.
Neil Redfearn's men fought back through a Danny Batth own goal and a fine curling strike from teenager Alex Mowatt. But it was sub Edwards who grabbed the headlines with a deserved late winner.
With a number of clubs above them struggling to put a consistent run together, Wolves may have timed their winning streak perfectly, and, standing just five points behind second-placed Norwich, will not have ruled out an automatic promotion place.
