I have brought a Digital boost gauge went to fit it today on my S2 and opened the instructions to find that it looks like its been written by a far eastern guy with no knowledge at all on anything to do with cars....
Anyway on the sender unit it a t-piece which obviously fits into a hose that has to be cut. The instructions say to fit this onto the 'manifold vavuum hose on car' any ideas which hose this is sposed to be and where its located. Thanks, Joe
