Core Policy Injector Pumps   Injectors  Turbo/Superchargers Cores must be in complete assembled condition. No missing parts either internally or externally. Cores must be like for like. That means the core part number must be the same as the purchased part number. There are some exceptions to this, so please inquire. Cores must be in rebuildable worthiness condition. Any damaged cores from misuse, abuse, alteration or contaminated fuel maybe subjected to a lesser value. Fuel Injection pumps, Injectors or Turbos assembled from junk or scrap parts are not accepted as cores Cores also must be shipped pre-paid All cores are on an exchange basis. We ask that you send in your cores once you have received your order. There is no core charge upfront. However, there is a core charge if we do not receive your core within 20 days from date of item purchase or if we deem the core is unrebuildable. Atlas Diesel Injection Specialists will also be glad to accept your core if you wish to ship in advance of your purchase. Please ship your cores carefully! Package them so they won’t be damaged. If your cores are very dirty and oily, please put them in a plastic bag. This prevents leakage during shipping.
