We oil injectors and blow the oil through them with air then re-oil again. This extra step specific to us ensures the oil gets to the Pintle to further avoid potential problems. The general answer and guidelines to the install timing question is as follows:
We suggest reinstalling the injectors within 30 days of the service date to avoid any potential issues. If they are left unused for too long, problems like sticking or leaking may arise. If you encounter any issues within 30 days of receiving the injectors, contact us to help identify the issue.
Bear in mind that some injectors may exhibit these symptoms earlier than 30 days. Side-feed and TBI injectors should be installed and used within 15 days as they are more prone to showing these symptoms sooner.
It will be your responsibility to handle the shipping costs back to us if you need us to revisit them for sone reason.
