In wet and muddy conditions, they beat the visitors by 20 points to 17, the Islanders clinging onto their narrow lead in the final nerve-wracking moments of the match.
Having trailed 3-10 at half-time, Jersey were put under pressure at the start of the second half, but fought off the challenges until they broke through the Leeds defence to score their first try.
A successful conversion brought the score to 10-10 with just 20 minutes to go, and an inspired Jersey team then went onto score a second try. Another successful conversion and a penalty kick from Michael Le Bourgeois gave Jersey a 20-10 lead.
But Leeds were never going to give up and another try and successful conversion brought them to within three points of the Islanders, a lead Jersey just managed to hold onto until the final whistle.
It was Jersey’s third win in the Championship Division and second over Leeds.
