My 2013 Civic developed a pinhole leak on the high pressure fuel line where it attaches to the fuel pump.
I'm considering repairing this leak using a fuel-proof sealant like Seal-All or JB Tankweld.
One idea, cover the abraded area with Seal-All to build it back to its original profile. Then, cover the entire area by wrapping a patch of JB Tankweld around it to protect it.
Or, the Seal-All could be wrapped in WrapIt Silicone tape, as it is fuel-proof as well.

Is there a better way to fix this, short of replacing the high-pressure line?
It looks like the connector was rubbing against the housing which damaged it. I'm not sure how that could happen as the connector isn't close to the body. Perhaps a rock or other foreign material got lodged above the pump and it came out when I opened the cover. A comment indicated a rodent may have done this, that is defintely plausible.
