^^ usually its not the line, I thought it was the gauge that they are worried about. The gauge could fail and cause hot motor oil from spraying,leaking into the cabin.
I was looking at getting mechanical because they are cheaper and provide better accuracy and generally faster response. But was informed by some local people that the auto cross scene where I live don't allow for mechanical gauges with out the isolator / diaphragm. But the isolator drives up the cost and makes it the same price as a full sweep electric.
