• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

My simple fuel sight tube on my S1 always indicates full no matter how much or little fuel is in the tank.

I suspect there is an air lock which I keep clearing by flying inverted a bit but it comes back. Anyone else had the same experience?

I'm trying to figure out what keeps causing it.

The line from the header tank to the sight tube is a braided hose (number 4 I think).
