You need something rated for at least 300 PSI. Copper is common, but you need a flexible section between that and the engine. As mentioned, grease gun hose is a cheap way to acquire such a thing. Gauges usually come with cheap nylon hose I do not trust at all.
5-6 feet should be no issue. I could see a really long line on a really cold day giving false low readings.
