Description
The PAI 431265 Injector Installation Set supplies the sealing hardware needed to properly reinstall fuel injectors on 1977–1993 International / Navistar DT466 7.6L inline-six diesel engines. Whenever injectors are pulled for service or replacement, the grommets, gaskets, and return-line hardware should be renewed — reusing hardened seals is a common cause of fuel leaks and hard-to-trace air ingestion on these mechanical-injection DT466s. This is a Genuine PAI new part, made by an ISO 9001-certified U.S. manufacturer and backed by PAI’s 2-year unlimited-mileage warranty.
