BLADDERS - NO TURNING BACK NOW

[DCarlton]

So far so good with my F's bladder install.  Access plates removed; vent tubes drilled out and removed; fuel cap adapter ring drilled out and removed; fuel senders removed.  Removing the fuel pickup tubes should be next.  Several types and layers of sealant built up over the years from patches.  More to come...

When you start torque wrenching the clamps, Tekton sells a compact one as I recall.

Interesting to see sealant applied to the inside of wing skin. I wonder what the thought process was there.

After looking at the repair work done on your tanks, no wonder you are putting in bladders.

If you stripped those tanks before you put the bladders in, you would probably gain 10 Lbs of payload.

Yep; nothing close to the beauty of a weep no more job. I'm trying to convince myself the extra 10 lbs of sealant will provide a cushion between the bladders and any sharp edges; along with the foam provided in the STC kit.

What I see is sealant put over sealant. And mystery sealant. And sloppy application. The only repairs approved in the maintenance manual requires the leaking area to be cleaned of all sealant down to bare metal. Then a bead coat of the specified sealant and after it cures, a brush coat of sealant. After that cures a top coat is applied. The repaired area should look like a brand new tank. That’s not what I see in your tanks.
