Uh huh. For those with any more smart *** comments, it is impossible to know which way this fitting should be pointed unless you are familiar with the firewall forward kit already. Most of us aren't. And since you install it with gorilla snot to seal around the fitting, it takes more than simply disconnecting the fuel line and loosening the nut.
I'm hoping I am saving someone some headache down the road by pointing the error out in the plans. Good on ya for trivializing an attempt to help out fellow builders.
