Hey guys, got a leak on my truck here, I can see that it is coming in where the evap drain hose exits the firewall. Now is there a chance that the gasket sealing the hose has failed?

Can I just put some RTV gasket around the rubber gasket in the firewall to stop the leak?

Or could it be the hose is plugged. Looks to me like the gasket has failed.

Anyone have any experience with this?

 

Sure, you can RTV it.
