What right angle fitting did you use?
If you go with a mechanical gauge then you want to make sure you use an isolator between the oil feed line and the gauge. Many tracks / events prohibit mechanical gauges that are routed into the cabin that have any liquids.
Using some line to locate the sending unit is a good idea I think I will do that on my build.
