Good To Know

Q: Can these fittings be used on high-pressure EFI fuel pumps? A: Yes, they are specifically designed to safely handle standard electronic fuel injection (EFI) pressures up to 100 PSI.

Q: Are replacement O-rings required when reinstalling? A: The integrated Viton seals are durable and reusable, but they should be inspected for nicks and lubricated during reinstallations.
