emp tank

The tank labled "emp" is a tank for additional fresh oil, for the oil injector/exchanger installed on these units. Every 30 Mins or so, it takes a bit of used oil and injects it in to the diesel fuel, while replacing it with an equal amount of fresh oil, back into the oil pan. Simultaniously lubricating the piston, and extending the oil life by approximately. 300 hours. I was unable to see the picture, however, from the sounds of it, this was a general dynamics model of the STT (lot 10), or it could be a lot 9 model produced by rockwell collins. Hopes this helps. P.s. not a deathray, they do not drive those around the country on flagged semis, those are kept elsewhere, and never transported in the open like that.
