And…They’re Done!
Had another GREAT day getting the last of the last of the sealant tasks for the tanks done. As you can see above, I sealed the right tank pickup and cover plate on. I opted to NOT use the cork gasket as many other builders have done. I also replaced the standard 8/32 x 1/” Phillips head screws with Stainless Allen cap screws and washers instead. IF I ever need to remove these covers while the tank is mounted to the air frame/wings, I can use a hex key rather than a screw driver. A provision that I hope to never have to use, but one that was cheap and easy to do, just in case.
Here you can see both, side by side, fully sealed. I did make a good fillet around each screw head with sealant after dipping each screw in sealant before installing them. Just extra hopeful leak free insurance. I also did a little fillet around the BNC connectors for the capacitive fuel senders, also just in case.
Here is a close up. The sealant is about the nastiest stuff made to man…other than used baby diaper deposits. I plan to let these sit for a week, then I’ll be able to pressure/leak test. If all goes well, we may be able to claim success. I was able to get these done about mid-day…which meant I could now move on. I was able to do just that. Until the pressure/leak check, I’m moving back over to the Wings. Hears hoping…no more sealant for a LONG time!
