Presumably , when these were being put together in the factory, The builders followed a plan of where the pipework etc was going. Are these plans available or, has anybody ever drawn up a digram of the pipework?
I am in the process of bringing my 1989 Gulfstream back to life. I was having issues with the fridge as it has been messed about with and the pipework changed. I was asking as to whether there were specific routes for the pipewrok and cabling.
