at which coloured dot should i cut the vacuum hose at would be much appreiciated if someone could help as i need 2 know what size t piece to get. thanks
right, this is really basic stuff robbo...... pull on the hose you have marked in blue, it will come away revealing a metal nipple which the hose plugs into,add your t-piece and your new vac line for the gauge and plug back in.....finished, peice of piss, cant be any easier than that....
