Do you mean the end of the hose tore when you were halfway through, or the hose ripped at mid-length? If it's the former, then yeah, just pull it back out. I had to do that and I had my frame strapped to my truck and it took two guys to yank it back out. Make sure you're thoroughly, thoroughly, thoroughly lubricating your hose and the frame tube. If you think you have enough, use more. I think they're recommending Liquid Wrench Silicone Spray these days. Plan on using half a can on each side (if not more).
If it's the latter... you're going to need a new hose.
