RE: Paccar fuel filter doesn't stay full Is it possible to get air in fuel system from the engine back to paccar filter? I'm pulling fuel from bottom of both tanks with all new fittings and hoses all the way to electric pickup pump. Concerned about boost pressure increased to 38 sometimes when it normally was around 32-34. Exhaust temperature has dropped about 75' from about 750 to 675. Fuel mileage down about .5 mpg. Thanks in advance for any advice. Mr. Hagg worked on last July, replaced ceramic fuel plungers on two cyl. pump along with mmII. | |||
