The Nigerians travelled to Algeria knowing that a win would take them above Etoile du Sahel into second place, and Gbenga Ogunbote got his tactics spot on.
Sunshine edged a battling first half and were on the verge of going into the break on level terms when Tamen found himself criminally unmarked as a low ball was crossed in behind the defence. He took full advantage.
Practically gifted that goal via some lax defending, Sunshine decided to reciprocate, in true Ramadan spirit.
Only the applause was missing as their entire back four stood around in admiration to allow Anicet Eyanga poke a bobbing ball home from five yards.
But Ukeyima ensured that Ogunbote's blast would wait for another day with a ripping finish into the roof of the net with 15 minutes to go.
The win takes Sunshine to seven points, three ahead of Etoile du Sahel, who host nine-point log leaders Esperance on Saturday.
