A topsy-turvy final saw Gould cancel out Yoni Shadmi’s early opener.
Moishe Hasid and Gould then struck after the break to put Maccabi Manchester Yellow into cruise control.
A defensive mix-up saw Andy Shaffer pounce late on to set up a grandstand finish.
But with Reich pushing forward they were hit on the break, with Gould making sure of the win in injury-time.
Reich’s woeful run in cup finals continues and director of football Michael Gaswirth said: “I think Reich FC is cursed as a team.
“This is the fifth final we've been and we've lost them all in the last five years.
“But there are no complaints from our part. We had the chances and at 2-1 down if we hit the back of the net, instead of the crossbar, it’s a different story.”
