I have the same RV and engine you do. I haven't had a fuel pump quit on me yet, but I was having problems starting mine a few months ago. I still have not replaced it but they are a known problem on these engines.
Best thing you can do is replace it with a factory cummins pump at about $170, or upgrade to an FRRP or something similar from FASS fuel systems. The upgraded ones are about $300 plus installation which is easy to do yourself. I am upgrading mine here in the next month or two before dune season.
Be careful, the lift pump goes bad and will rapidly take out your injection pump with it. That's a $3,000 part installed. Be on the safe side and just upgrade pumps.
