i bought a used 01 dodge 2500 back in 2011, has 141k on it when i bought it. first month had it fuel pump and injector pump went out. replaced with one them air dogg fuel pumps and factory injector pump. internet said the factory fuel pump was the demise to the whole system that the factory pump didnt supply the injector pump with enough pressure, who knows. Good thing the Air Dogg has a lifetime warranty cause it ate motors put 5 motors on the thing until i sold the truck last year. Yeah they were free but still the hassle of the truck being down. Other than normal maintenance brakes/oil changes/filters ect i put ball joints, new hubs on each side, one short side front axle (hub went out an eat the axle), the injector an fuel pump, water pump, A/C motor, an needed a dash. Sold last January for 12k and has 237k on it. Looking for another diesel to me im leaning to the 6.7 ford or the duramax
