Core Information-

If you are sending in your injectors for re-manufacturing, do not accept the core charge when purchasing. After completing your purchase send your injectors to F1 Diesel to be re-manufactured.

To obtain core charge refund please send equivalent core injectors to F1 Diesel upon delivery of purchased injectors. 

Please carefully package your injectors for shipping.  We recommend using bubble wrap to contain each injector and taping the boxes up very well.  Packing failures are a major cause of damage to solenoids or nozzles and even loss from broken tape or an injector that pokes through the box during mishandling by shippers.
