It can happen on the 12 valve Cummins too. Difference is they run a mechanical lift pump that's much less prone to failure than the electric ones. However same thing happens, a guy replaces the lift pump after the engine starts acting up. It may run fine for a while but sooner or later (usually sooner) the injection pump goes. Those injection pumps are designed with the expectation that they will be supplied with pressurized fuel. Start making them suck fuel from the tank and they die real quick.
