Help...when installing new Stainless Marine therm noticed there was no opening for the existing sending unit as on the stock set-up. Only opening I could find was on the rear top-end of manifold. Manifold is stock 1995 454MAG. The unit works but only at idle power. When power is applied temp goes below 80degrees then rises again to 100-120 or so when at idle again. The stock system worked great norm temp 140-160. wink The h2o in the rear of the manifold is cooler so I believe i'm getting those readings? Can I get my old readings again, need a different type of sending unit or adapter? Thanx... :confused:
