my mates dad owns a import business and spare parts yard and he gave me like a whole bunch of gauges, now i know wat all of them do except for the vacuum gauge, can sum1 tell me exactly wat that does? and will it work on my N/A car or am i gonna have to give it away or use it just becoz it lights up LOL

A vacuum gauage meassures the vacuum in the inlet manifold. It will work on an N/A fine.
