nathan.a Posted October 25, 2017 Share Posted October 25, 2017 got a 2013 CXU612 that ran out of fuel on the freeway. gauge said half a tank. driver side tank has about half a tank and the passenger side tank was empty. we put fuel in the right side tank and got it running. its pulling from the right tank into the left tank. I changed out the tank vents and filters. with tractor running I can see bubbles and what looks life fuel going out of one of the tubes inside the passenger side tank. any ideas??

TOMD Posted November 6, 2017 Share Posted November 6, 2017 check to see if truck has dual draw. lines from each tank go to a tee then to engine. if has that loo for obstruction in driver's side tank. if it has single draw look at cross over line or shut off valve at bottom of one tank turned off.
