Tomas Francis started ahead of Lee at tighthead that night but the latter was introduced in the second half and did a fine job of shoring up the front row.
On Thursday against the Pacific Islander the 22-year-old Lee - who is still recovering from a lower leg injury - will again come off the bench with Francis in the starting No.3 shirt.
But the Scarlet - who was restricted by injury to only six appearances in the GUINNESS PRO12 last season - is confident the forwards will get it right this week.
"It was a tough day at the office," said Scarlets tighthead prop Lee, who went on as a replacement early in the second period.
"We always knew they were going to be a difficult pack to go up against.
"We have to sort out whatever we need to get right and then take it into the Fiji match on Thursday. The problems are 100 per cent fixable.
"We lost most of the hits in the scrum and ended up soaking up the hits, so this week we have to get our speed right going into the scrum.
"No one is going to be happy with Wales coming second in the set-piece. So we will get it right this week and get our speed back.
"We discussed it in the changing room after the game. It was down to our mistakes. Our speed on the hit wasn't right."
