Has anyone ever had a problem with the oil pressure gauge after installing a Mod Motor in a Fox? In a few days I'll be starting my Mod Motor for the first time with the instrument cluster installed. I've got an '88 dash and a '98 engine. The Mustangs Unlimited catalog lists different oil pressure sending units for the '88 and the '98. Does the '88 sending unit have the same electrical resisitance range as the '98? I've come this far and don't want to blow out the oil pressure gauge because it wasn't matched to the sender.
