well my first post was about nine months ago with the purchase of the fuel pressure regulator and filter...got my plate and insurance yesterday afternoon and set off this morning on the maiden shake down trip and went fourteen miles of 45 to 50 mile speeds through commercial areas. no high rpm nor quick acceleration. all gauges showed good numbers. checked for leaks and other than a slight valve cover gasket all seemed fine. no water leakage. not really hot this morning...maybe 85.... so not like out on a 95 to 100 degree day. im hoping that the front opening in the ruf bumper cover will allow enough air to the radiator. do not wish to alter a genuine Ruf piece but will if necessary. the ECU turns the fans on at about 195 degrees. i could tell that the modified ls7 was really wanting to go!! not yet???
