Help with fuel line

[lesslethal]

Good evening to you all. I have an m35a3, that has a leak in the fuel line that extends from the fuel filter up the firewall and into the back of the motor. Does anyone have a suggestion for loosening the top fitting? I can reach it from the top with a wrench, but there is no room to them loosen. Thank you.

Use a "crows foot" socket.

I appreciate the help. I don't have the crows foot socket set. Will buy today. Thanks again
