Well for about a year now my cummins has been loosing idle rpm's i would adjust the idle stop and it would be fine for a few months then i would have to do it again until last saturday went to publix and she almost did not start [2'nd time this happened at a publix, changed fuel filter the first time it happened, 3000 miles ago which i figured fixed it] well there i go thinking again well i got her home adjusted the idle again and figured done deal,went out sunday fired her up and the idle was worse than before i touched it saturday soooooo i walked away pissed thinking it was the injector pump [800-1700 dollar part which i don't have] got a ride to work all this week and reasearched on line what else it could be came to the conclusion thru my research it was the lift pump [Geno's Garage/Turbo Diesel Regstrie] ordered one put it in yesterday [warning if you are not into heavy mechanics don't try this your self] well it is back up and running has more pep the idle is where it should be. Only time will tell if there are no other problems with it shes getting old and thing are starting to give up.Next project is rebuild the steering components shes a little loose. For those of us who have cummins engines Geno's has a lot of stuff for our trucks and reasonable prices example my lift pump was 147.00 local auto parts - 102.00 rock auto - 99.00 genos plus shipping/ fuel filter 29.95 - local auto parts 21.00 rock auto 15.00 genos plus shipping. both parts ran me 130.00 includes shipping. NEXT MODS- full set of guages [egt/boost/trans temp/fuel press] a pillar guage pod.There is a lot of info on genos and TDR for our cummins 89-2011 i have learned a bit about the 12 valves for sure.

Thanks ya'll, for those of us with ctd's there are many tsb's and articles for our trucks especially the newer 24 valves.If you guys aren't running a fuel pressure gauge you should think about one during my research i found out that my lift pump problems won't hurt my injector pump but the newer trucks can have damage done by loosing fuel pressure.From my research i have gathered that constant maintance and clean fuel is key to dependability more so for the newer cummins. I'm very anil about my maintaince but things happen. Thank's Adam for the offer i'll keep that in mind.
