"I was never informed where to ship back the core then I shipped to diesel power products and I pay 33 dollars for shipping and in top of that diesel power products charge me an extra 13plus dollars to ship the core to the manufacturer very over all I should just not return anything and let manufacturers charge me the total of 50 dollars and without have to go through all that hassle. I trusted them because I had already buy many parts but don’t know if I wish to keep making business with Diesel Power Products"
