Recently purchased all my gauges from Genos Garage and finally had them installed. All worked well when the fuel pressure started to drop. Caught a dying lift pump early. However the exhaust temp gauge started to act up and was sticking around 700 deg. Contacted Genos they promptly sent me out a new one and a box to send old back. Could not ask for a better customer relationship than that. Hope that everyone else has as good an experience as I did. Jim
