All Injectors and CP3 Pumps are sold with a limited time core exchange policy, which means you must return your used Injector(s) or CP3 Pump (cores) to us within sixty (60) days of the delivery date to receive your full core charge back. Any damage to the injector solenoids, burnt, or disassembled units will result in a core refund deduction or no refund at all at the discretion of LDS. This also applies to the CP3 Pumps, if the fuel pressure regulator (FPR) has broken tabs or is damaged (smashed) during shipping due to improper packaging, this will result in a core refund deduction at the discretion of LDS. If a CP3 Pump Core is missing the freeze plugs, this will result in NO CORE REFUND. Notice: Failure to return injector core(s) to LDS within 60 days will void all product warranty.

Core Exchange Chargeback Policy

  • Cores returned within 60 days of the delivery date will receive a full core charge back.
  • Cores returned between 61-90 days will receive only 50% of the core charge back.
  • No core refunds will be issued after 91 days.
