You will need a fuel pressure gauge , at idle it should read around 35 lbs, remove the little vacuum hose and it should read around 45 lbs , if you notice gas in the vacuum hose at all , it is bad , and you may want to use a vacuum gauge to make sure it doesnt bleed down , also you can shut it off and make sure the pressure doesnt bleed off , it should be above 20 lbs after an hour of sitting ....if that tests good its ok ... Nismo has a nice adjustable pressure regulator avaliable for the KA's !!
