• 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).

I have a used PN 3090050 aux pump setup. It was working good on a IO-320 RV when removed. I contacted Don at Airflow Performance and he will flow test and check it out for $35.00. They don't sell this exact pump anymore but one just like it. These use to be $600+ like this one...the new version is only $390 so I figure a good used system ought to be worth $215. (You will have $250 in it if you ship to factory for the flow test and check up). Shoot me a PM and I will post pics later today.
