X300 Barke pipes on survo

Hi guys, need some one with an X300 to help me out a little here!! Basicaly I have upgraded from the old XJ40 brake booster to the x300 vac unit, but the thing I need to check is the position of the brake lines...... do the front brakes pipes go to the fitting towards the front, or towards the rear of the master cylinder?? Don't realy want to get them the wrong way or things could get very interesting!!!

Cheers
Jono
