Please can some one help, my mk1 aircon system does not work, has been checked by a aircon company in Alton,hants, who told me I had two leaks in the pipes, 1 pipe is the suction pipe assy, 2 pipe is the liquid line assy, my question is can anybody tell me which pipes these are, the man wouldn't tell me because he want to do the work at a price of £562.81, very very expensive, I have some second hand pipes but need to know which ones I need to change, so if anybody knows it would be a great help,Brian
