502 efi temperature sending unit?
I have a 98 353 fastech and 1 motor is telling me it is hot like 190 f at 4000 rpm. The gauge will climb and jump back to 160 or so instantly. Never any alarms going off. I shut it down and felt the hoses. The hot one felt warmer than the other, but not concerning hot. I'm not sure I believe the gauge with it jumping around. Sending unit? where are they?
