Brake Line

Purchased a brand new rear off side brake line which feeds into the calliper, after installing and began bleeding the brakes fluid was gushing out. It seems to be pouring directly from the calliper line feed, everything is solid and tight. Any ideas on why this could be happening?

This happened to me when i overtightened it. Ended up needing a new caliper as the threads in the caliper were stripped. Make sure the feed has no movement in it?
 
I had a feeling this would be the problem! There was no movement in the feed but it was over tight through frustration. I'll venture round the scrap yards for a caliper this weekend.
