i have a BEKO DRCS 68W tumble dryer.at the back of the dryer there are 2 flex hose pipes,one coloured dark grey,the other white.they are on 2 connections,2 at the top,& 2 at the bottom.i have to renew the pipes as the original ones were missing and i have no manual.my question is on which connectors do pipes fit onto,i.e.top left to bottom left top right to bottom right
