Good To Know

Q: Do these caps fit all fuel injector rail ports?A: They match common O-ring-style injector bores; measuring your rail’s port diameter beforehand helps ensure a solid seal.

Q: Can the block-off caps be reused after fuel contact?A: Yes, the polymer is formulated to resist fuel absorption, so you can clean and reuse the caps through many service intervals.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
