RE: air/fuel ratio gauge
is it like those clips that "piggy back" or splice into the wire coming off the O2 sensor?
how does a vacuum gauge work? does it just attach to the intake manifold or a random vacuum line? how does knowing the vacuum help you?

RE: air/fuel ratio gauge
it lets you know relatively how open your fuel pressure regulator is.... more vacuum better mileage... and yes it attaches to a random vacuum line...my gauge came with plenty of hose to make it down the a-pillar, thru the firewall and across to the fuel regulator....thats where i have it tapped....
