• 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.

Hello All,

New guy here. I have a Pitts S1S with Christen manual fuel pump. The threads in the pump housing where the filter bowl attaches are shot. Aviat tells me the pump is no longer made. They gave me the name of a guy that rebuilds them. I spoke to him about cleaning up the threads and replacing the filter bowl. Might work, but the treads are pretty chewed up from what I believe to be an overtorque situation. Any ideas to save the unit? Anyone have a complete one for sale?
