Hi. I have been busy swapping engine & trans on mine so was easy to get some photos for you! Spent far to much money with some shiny new parts - as well as cleaning & painting front subframe, steering rack & anti roll bar etc. Drives really nicely again just rear axle to play with now!! You want to look down below where the vacuum hose joins the engine (passenger side rear of engine) it has a jubilee type clamp to retain it that's where both mine had cracked. It's a time consuming job to remove the tube as battery & tray, header tank need removing to get to it for a start. I was also smelling the fumes from it but not anymore. The new one in the image shows the convoluted section that is not on the old one. Hope these help
