2S 2095 320 410 8,23,02 21 : 19 P.05 <br /> Remarks: (Secondary test; page 2) The gasoline tank secondary test was <br /> started at15.2" vacuum. After 20 minutes, the reading was slightly below <br /> the 15" mark on the gauge. The test was allowed to continue to a full 60 <br /> minutes. The final vacuum reading was 12.2". The Diesel tank annular <br /> space was tested at 15.0 " vacuum. After 30 minutes the reading was <br /> 12", indicating a leak somewhere in each system. Another access to the <br /> annular space exists on both tanks. They are 2" risers on the far ends of <br /> the tanks and they are capped with threaded fillcaps with cork gaskets <br /> that were common during the time of the installation. These could be <br /> leaking, allowing the loss of vacuum that we saw today. A retest should <br /> be performed with these risers capped with 2" pipe caps to ensure a good <br /> seal. <br /> The big concerns of the day are the electrical tape holding the sensor <br /> above the liquid gasoline in the secondary (annular) space, the liquid <br /> itself, and the failure of the Campo-Miller Line Leak Detectors to properly <br /> monitor the product lines. <br /> Test Technician: 79" _ - Mike Dotten, License 90-1068 <br />
