A few weeks ago I landed and refilled in Deming, NM, on my way from Texas to
AZ. After takeoff, at about 1200 ft AGL or so, I noticed fuel streaming down
the right wing. Normally I sit low enough that I can't see the fuel cap on
that wing but when I sat up a bit I could see that fuel seemed to be sort
of bubbling out of the center of the cap. After landing I was unable to see
any reason for this-the cap was seated and latched just as always. I removed
it, cleaned of the o-ring around the outside and replaced it. No problems
afterward and it has never recurred even though I always check after takeoff
and every now and again in the air.

I also had a fore-and-aft movement of my nose gear leg that seemed to be
caused by the steel tube insert that holds the upper end of the nose gear
leg in the motor mount being a few thousanths large at the lower end. The
vibration occured as the mains touched but before the nose wheel would
touch. Replacing that steel tube insert cured the problem.

Greetings,
Does anyone know if the cowlings for the -6, -7 & -9 airframes are interchangeable?
In other words, are the firewall dimensions of the side-by-side airframes the same
(or at least pretty darn close)?
Thanks for any input,
Konrad

yes for the 7 and 9; probably not for the 6.

Yep, this happens to me too whenever the tanks are full. There doesn't
seem to be a way to prevent it other than leaving the level down a bit. I
tried tightening the center nut, but it doesn't budge, and as you say, it
appears to be leakage around the center bolt anyway. If I ever find
alternative caps that fit the stock neck, I'll swap them out. You might be
able to machine a groove for a small o-ring around the center bolt if you're
into a mini-project.

Remove the nut on the bottom of the cap. Now while holding the top of
the cap unscrew the bottom of the cap. The nut is just a stop nut. The
bottom of the cap is threaded onto the shaft. There is an O-ring on the
shaft also, well, at least on mine there is. Lots of corrosion happens
inside the cap so this is a good time to clean them up. Goober
everything up with fuel lube and put it all back together. Don't put the
nut on until you have adjusted the O-ring tension by screwing the bottom
of the cap closer to the top. A little trial and error works here. Once
satisfied that all is well replace the lock nut on the bottom.
My caps have set out in some torrential rain and never leaked. I don't
check the fuel level visually after a rain as there is water standing in
the groove around the cap and removing the cap would allow the water
into the tank. Keep the orings slathered in a light layer of fuel lube
and you should have leak free caps. At least it works for me.

Albert..... you lost me on that one. I was unaware that there is an insert in
the nose gear socket. I thought the gear leg just fit directly into the steel
tube that is a welded part of the motor mount.
I, too have found that if I fill my tanks too near the bottom of the filler neck
I get a small amount of fuel streaming back from the cap for a bit on takeoff.

When Van's have the motor mount welded up, the socket for the nose gear leg
is made up of a long tube that has 2 smaller inserts or sleeves welded
inside of it-one at the top and the other at the bottom end. Unless you have
a reason to be replacing one or both of those inserts because of a loose
fit, you would not likely ever find that out. BTW, it take a real hard
bounce on the nose gear to create a loose fitting nose gear leg socket. As
they say, don't ask me how I know.

As some of the others have stated on the various RV lists and as I
accidentally discovered when leak checking my tanks, the center nut is a
locking nut. Loosen the lock nut and you will be able to adjust the sealing
tension by rotating the main body in relation to the lever.

Okay, now I get it. I recall the collars at the top and bottom. But since
they are welded in, they must not be too easy to replace. Odd that you were
feeling some shake before the nose gear came down.
I get a little minor, short duration shimmy at times on rollout even though my
damper is set as the instructions say, but I think it is from a wavy runway
surface. Most airports I don't notice it, and it is not bothersome.
Thanks for the tip, Albert. That is a new one on me.
