Thanks for the replies fellows. "Wonder the Thunder Pig" is currently at 153,000 and I noticed yesterday the pump seemed to be on the loud side. It also seems to labor under load, (climbing hills and accelerating from a stop). Pretty sure it's the original pump. Didn't know if it was me or if that was a warning sign of problems in the near future. I think for the sake of not being stranded in the middle of no where in the middle of the night, I'll be dropping the tank and replacing the pump this Saturday.

Another sign of a fuel pump about to quit is feeling a sudden, inexplicable, and urgent need to completely fill up your gas tank even though it has enough gas in it already. If this happens you should not shut the engine down until you drive to wherever you're going to replace the pump. If you feel that you must fill up the tank right away and can't fight the urge you can leave the engine running while you fill up.

Just changed it about a month ago.

Knowing you, I think you are joking. I presume you expect having to drop the tank to replace the fuel pump and by Murphy's Law, you will need to do it just when the gas tank is completely full!

But then again, sometimes you are serious, so one never knows!

I have an AirDog to go in to replace the current lift pump.

Cummins did their best to make a great engine, and Dodge did their best to screw it up with a poor lift pump, then moved it into the tank and still more problems.

A mechanic who is up on the technology can monitor the waveform of the pump circuit with a scanner and tell when it is underperforming, i.e. about to die. I don't have a link handy, but it shouldn't be hard to find.

This is pretty much true, but requires an oscilloscope or equivalent tool. Some scan tools will have that built in, but not all and not any cheap ones.

The blame for the lift pump goes to Cummins, not Dodge. Cummins supplied the Carter-sourced lift pump mounted on the block. I agree that Dodge's in-tank pump wasn't very good.

And frankly, if I ever see a real mechanic who gets paid on the flat rate ever did that in a real life (vs youtube) I would probably die of heart attack! Seriously, driveablity specialist are extremely rare breed and you won't find them employed by a corner gas station or a generic car dealer.

The best driveability guy I ever knew was working at a gas station when I met him, but he was salaried, not on flat rate. I worked with him for a few years and in that time I never saw him put the scope on a fuel pump.

sometimes when a car doesn't start due to a failed fuel pump, you can smack the gas tank, and it will make the pump work again.

But you can't count on this method.

Our expedition had no warning. Just started, chugged for a few seconds, and then died. Fortunately it was right across the street when this happened, but it gave me no warning when it did.
