now can anyone tell me the best injector pump and and lift pump to buy... I have a 2002Dodge cummin diesel automatic... would appreciate any info... do I buy these at my dodge place--factory--or do I get a cheap set --what is the best? I don't want something that is real expensive that I don't really need--but---I want something that will do the best job. . I drive a lot on dirt roads where I work... thank for your info
