If it is a Lift pump you need there are a few options, I am on my 4th one so I have been through this Car Quest has them made my AirTech for $187. 35 which a little more exspensive than if you was to buy from say a Freightliner dealer which comes in a cummins box for about $127. which is still cheaper than one from chrysler at about $300, however Car Quest pumps come with a lifetime warranty(ask though because some car-quest warranty differs from others). If a vp-44 pump is what you need most fuel injection places have them rebuilt with exchange for around a grand give or take. Good luck
