After a 34-24 defeat to Ulster last weekend, the Westerners will hope to go one better and have named a matchday squad featuring players from nine Connacht clubs.
Lee Kilcoyne starts at loosehead and will pack down beside hooker Ronan Lydon and tight-head John Hughes.
Conor Ryan joins Rory Glynn in the second row, while the back row features Blayze Molloy at blindside flanker, Robbie Byrne at openside and captain Max Flynn at number eight.
Ben Matheson and DJ Hession form the half-back pairing with Charlie Naughton, inside centre, and Sean Fox, outside centre, are selected in the centres.
Cormac Lyons and Cathal Kelly are selected as wingers with Cody Farrell operating as the full-back.
Charlie Leonard, Sean Hopkins, Charlie Byrne, Alistair Hill, Eoin Kelly, Joey Tierney, Ryan Roache and Eoghan Flannerey form a strong replacements bench.
Connacht U18 squad to play Leinster at Energia Park, Donnybrook at 3:30 PM on Sunday, August 29th.
