The type of OP gauge I was recommending has no sending unit that could fail. A Mechanical gauge has OP sent directly to the gauge itself via a plastic line and fitting where the sending unit thread into. The biggest danger is the line springing a leak. If you have a problem with a mechanical gauge it is way easier to tell and in my opinion more reliable than all other types of OP gauges.

Why not have the best of both worlds and install a T fitting and use the light and the gauge. What ever blows your skirt up.
