A host of international stars have already been confirmed for the game which is a repeat of the fixture held at the home of Gloucester Rugby back in May 2008, including Fuimaono-Sapolu's club team mates Akapusi Qera and Mike Tindall.
It's the 31 year old's first call up for the famous invitational side and Fuimaono-Sapolu admitted that it fulfills a lifelong ambition.
"I'm absolutely honoured. When I was young, I had only two goals in rugby. I didn't want to be a professional player, I just wanted to play for Manu Samoa and I wanted to play for the Barbarians.
"They're a team who draw players from all over the globe, they literally represent the world of rugby. It's a huge honour for me."
Eliota went on to explain that it was actually a childhood love of basketball that had led him indirectly to watching the Barbarians and that the attraction was instant.
"One of my favourite sports teams to watch when I was young were the Harlem Globetrotters. I loved the way that their primary goal was to entertain but that they were so good that they could beat the professionals.
"For me, that's what rugby should be about and that's what the Barbarians stand for - playing quality rugby but, above all, entertaining people."
Entertaining is certainly one adjective that can be applied to Fuimaono-Sapolu's contribution to Gloucester's success on the field during his time at the club, particularly last season where his sleight of hand confused many a defence.
"I think the way they play is perfect for me. I've always tried to be a bit different in the way I've approached the game.
"Obviously the professional game is all about winning and the Barbarians are a little bit different. It's a bit harder in a way as you want to win but also entertain at the same time. I'm really looking forward to it."
And, with a move to Japan in the offing, it's a final opportunity to bid a fond farewell to Kingsholm and the Gloucester supporters.
"I missed out on the last home game of the season and obviously don't know whether I'll play in the Kingsholm game yet.
"But I'd love to be involved and finish off playing my style of game at Kingsholm. It'd be a great way to say goodbye to some fantastic supporters. I hope I get that chance.
"It'd be even better if Tins and Q are involved as well. I really hope we all get the chance to take the field together. That would mean a lot."
