Replace or Don’t (Fuel Tank Problem)

[Jhogan0101]

I noticed when filling up pilot side main tanks ALL the way i get a small fuel leak.
Upon inspection with a boroscope, i think the leaking is coming from the small section of hose ON TOP FRONT (not bottom hose) area of the mains No cracks on top of the tanks were noticed.
I believe this hose is to allow the inboard main tank to equalize air.
To gain access, the top leading edge screws would need to be removed along with the screws holding the metal on top of the wing.
I really dont want to deal with all of those rusted/painted over screws
What would you do?

You already know the answer to your question.

Leaks don’t fix themselves, and will only get worse.
Prep the screws: cut the paint, warm them up, soak in Kroil.
Buy new bits and a new extractor kit.

You are correct sir…. Unfortunately…

This is what mine looked like. 1973 C337G about 2 1/2 years ago. Hopefully the pic attaches.

Aircraft Tool Supply ATS Screw & Bolt Remover (10") is the screw removal tool needed for the job along with a rivet gun. I use only IRWIN IWAF31PH220 20-Piece Impact Screwdriving Phillips #2 in high torque areas like the wing panel screws. While she was opened up i would change the gaskets on the fuel senders also. I always apply a small bead of PRC on the gasket and screw heads of the senders. JoeS

ps. there is a wing and tail boom support instructions in the manual.
