I discovered gas was coming out of the top of a fuel injector this weekend. I had the injectors cleaned by RC Fuel Injection out of CA a while ago so I’m thinking it’s either a wrong sized o-ring or I did a bad job connecting the injector to the fuel rail (I’ve been chasing down a raw gas smell for a while which is why I was in the engine bay this weekend). I’m going to replace the o ring with an OEM one and make sure the injector is fully connected, but is there anything else that could be causing the leak from the top of the fuel injector? I’d like to know what all I should have on hand so I don’t have to do this twice.
