• 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.

Hi.. plumbing.. I know that you should have no lube., graphite powder, tape or any such additional things added to a flared tube fitting...

but what about other attach points - example the fitting that goes into the fuel tank, AN fittings that go into the gascolator, shut off valve, fuel pump etc..? I have an airflor performance electric fuel pump setup, and it looks like theylube up some of the connection points with something, but I'm not sure what it is, and when/where it should be used.

help, thanksEdited by: macwolf
