The oil sender you are refering to lights up the oil light. It is located on the left rear side of the motor and can easily be seen from underneath. It is very common to leak and it can be removed, disassembled, resealed with silicone (sensor safe), and reinstalled. When it leaks it looks like the oil pan gasket is leaking. You may also have to replace the wire going to it as it is usually pretty crisp. The sender by the oil filter is for the gauge. If it is leaking Marty Maier has an improved replacement that makes the gauge more accurate.
