Have you tried yelping when the dog bites you? Keep a toy handy and put a toy in his mouth when he tried to bite you. I find this helps alot also dont give him any attention when biting, if he wants to bite you he doesnt deserve attention and he needs to learn that. so next time he bites you yelp loud and push him away and ignore him. He will eventually learn that he doesnt get any fuss when he bites.

Sounds nasty but sometimes it takes a older dogs to tell them off to establish their position in the house. Most dogs will make alot of noise but not actually damage. Maybe seperate them while being fed? one of my dogs is quite food agressive with my other dog and it works well in my house. Its a bit annoying but it ensures they are both safe without any fights.
