I am in the process if finding and fixing seeps in my port side tank. I see two leaking rivet heads on the outboard portion of the tank in the area of the outermost bay. Weird that it does not leak from the seam of the rear baffle but at the rivet heads of two rivets that don't even go into the tank, just the outer flange. At least I know where they are leaking because I can see the fuel. Problem is that I also have some kind of seep somewhere on the innermost (next to the fuselage) part of the tank. When on the plane I can see evidence of fuel seeped from somewhere there showing up on the bottom skin. I have had this tank on and off the 9A now four times hunting these leaks.
The seeps are so minor that it takes days for some evidence shows up on the bottom skin but the seep so little that none ever reaches the floor of the hangar. I have the tank out now...again trying to detect where the innermost seeps might be from. The tank is capped off, filled with 18 gallons and sitting on a work table anchored in such a way that it is oriented exactly as it is on the wing. The filler cap is on but not sealed so no pressure can build in the tank. Three days now and no evidence of seeps but it has been cold, near or at freezing. I am wondering if it only leaks where the temp is higher?
I cant fix what I cant find...anyone else been through this?
