Fuel was leaking (spraying) from the o-ring behind the schrader valve on the fuel line. Are there any suggestion to repair it with out replacing the fuel lines?

I already took out the schrader valve replaced the o-ring, coated the o-ring with RTV and reassembled. I ran it this week without any problems, but wanted to see if there are any other suggestions.

Thanks
