It was cold and rainy all morning. The temperature in the hangar was around 38o,
or in other words, it was cold. I took
the fuel tank filler tube back with me today.
I looks pretty good. I laid it on
the wing and got the necessary tools and supplies to reinstall it to the turtle
deck.
I also shortened the fuel return
line by fractions of an inch.
I mixed up some Pro-Seal and then put some Boelube
on the underside of the turtle deck here the filler tube flange attaches. I attached the tube until some of the
Pro-seal began to squeeze out. I removed
the excess with a paper towel and MEK.
After cleaning up the filler tube and making
sure everything was OK I decided to seal the holes drilled in the fuel tank
cap. After constructing the tank it was
suggested that you drill 3-small holes in the fuel tank cap. The cap consists of an exterior and interior
plate with a rubber ring along the edge between the halves. As the cam handle it depressed it pulls the
top and bottom of the cap together and expands the rubber ring. This action locks the cap in place and seals
the tank. The holes relived the pressure
in the tank when climbing or descending.
With the new tank vent system in place there is no longer any need for
the vent holes in the tank cap. I
disassembled the top and bottom parts of the cap and used some of the Pro-Seal
to fill the holes. After I install and
seal the rear window in place I will make the final attachment of the
filler tube to the tank. After working on the tank
cap and setting it aside for the Pro-Seal to cure I turned my attention to the
tie down rings under the wings. Using my
creeper I got under each wing and installed the tie down rings. They are parallel with the airflow under the
wings and I am planning to have them painted in place.
