Installation Notes and Tips

Confirm upper-position application before installation and compare the old seal to the new O-ring for size and profile. Clean the injector and mating surfaces thoroughly before assembly, and inspect the injector bore for damage or contamination. For best results, replace the seal during injector service rather than reusing an aged O-ring.
