I have a 2500 Ram with the diesel HO engine. When the tank starts getting low, the engine will quit if idled down. Low fuel light does not come on and the computer indicates plenty of fuel remaining as well as does the tank indicter. What has occurred is traveling on the interstate and fuel indicating about an 8th of a tank, I exit on an off ramp and come to a stop sign and the engine quits. I have to bump the lift pump a few times before it will start and so long as I have it running at a high rpm it will keep running. What pump other than the lift pump, up on the fuel filter, does it have? Is the tank being pressurized to force fuel up to the engine? Does the lift pump run all the time? Could I have an air leak in the tank?
