just recieved a 6 gauge set of faria dress white gauges that i ordered mainly cause my tach was jumping around alot and a couple cracked lenses are these gauges reliable
if your asking if Faria gauges are reliable, the answer is they are as reliable as any other brand. are they accurate - NO none of the gauges are accurate. they are accurateish.
another question. we assume you put in a new impeller when you did the thermostat, correct?
