How long will a 12v Cummins last?
So, the general consensus seems that a Cummins engine’s life expectancy is from 300k-400k miles, but if you follow the correct steps, you could, and should have some sort of control over the life span of your engine, and we don’t think crossing your fingers will really suffice.
What is a 12v p pump?
The P-Pump, as Tyler puts it, is “basically a little engine in itself.” Driven by the engine’s cam gear, the P-Pump is an injection pump that gets fed fuel from the lift pump (which takes fuel from the tank). The injection pump’s six plungers—which ride on a camshaft in the pump housing—move up and down in barrels.

What kind of springs do I need for my Cummins pump?
It’s important to note, however, that stiffer valve springs need to be installed in the head if you plan to spin the engine beyond 3,500 rpm or run big boost.
