Does anyone know how I can detach or remove the fuel tanks from the wings? I unscrewed the screws on the wing but the tank refuses to budge.
Due to a fuel leak I need to remove the starboard tank. Fuel was dripping from the trailing edge of the wing root.
Thanks.

Hi George,
I think there might be a hand full of AN3 bolts that you'll have to remove from the aft side of the spar before you can drop the fuel tank. On the RV-8, there were a lot of bolts. A lot. I can't remember if the -6/-4 have the same arrangement, but it would stand to reason.

I have had the honor to perform this task numerous times.
There are no rear-baffle-to-spar-bolts on the six wing tank, so you are almost done.
There is a bolt at the front and rear on the inboard side. These attach the inboard tank rib to the airplane. In the front it is a bracket, and in the rear it is a tongue fitting in to the fuselage carry through aft spar. You must remove the wing fairing to get to these.
Even when you get all those fasteners out there are still some traps.
there are a bunch of those screws which are dimpled these dimpled holes do not want to let go of the recessed holes they go in to. you sometimes have to persuade them with a sliding piece of shim material. I use a plastic putty knife to pry the skins up a little to clear the dimples.
Further traps include: forgetting to unscrew and disengage the fuel lines and vent lines, and lastly the fuel level sender wire.
Good luck. The fun is just beginning. wait til you drill holes in the aft baffle and start cleaning out the pro seal.

Sorry, but RV-6 and RV-7 tanks are attached differently.

George:Once in a while a question comes up which I can actually answer.
Sorry about your fuel leak - I believe the RV-6 has the same fuel tank attachment arrangement as my RV-7A - in addition to removing the screws which attach the tank to the top and bottom of the wing - you must also remove a number of AN-3 bolts which fasten the tank to the main wing spar - the back of the fuel tank is attached to the front of the main wing spar by a series of "Z" brackets which are bolted to the rear of the tank in front of the bracket and to the front of the spar at the rear of the bracket - you can access the bolts at the rear of the brackets by opening the inspection panels on the bottom of the wing - access is not difficult once the inspection panels are removed - the bolt heads will be obvious on the back of the spar - the brackets will stay bolted to the tank as it is removed - Good luck with the leak.

Close, but don't need to remove the rear spar bolt to pull just the tank. Just the screws, bolt at leading edge under wing root fairing, and the tank connections mentioned below.

Well said. Two sentences covered it all.
The more I run on the greater the chance of error.
Thanks.
