I am going to install a temperature guage and am not sure where the sending unit is. Is it the one that screws into the block next to the fuel pump or the one that screws into the top of the intake manifold? If it is one of these then what is the other one? And where is the oil pressure sending unit? I have a 1972 302.
The one next to the fuel pump is the oil sending unit (oil pressure). The temp sending unit is located in the intake manifold.
