The oil pressure gauge in my 1988 GT 5.0 isn't working, I updated the gauge cluster to one from a late 1989 model. The gauge stopped working in the previous one also. I replaced the oil sending unit with a Borg Warner. This car also has a low oil sending unit in the pan, could these two be related as far as the problem is concerned.
