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.

Howdy All,

I recently brought home a new S1C project and need some help with the fuel system. Doing an engine swap from a 290 to a O-320-A2A w/a PS5C. The previous owner didn't reinstall most of the inverted system after the rebuild and I'm trying to get it back together.

Plane came with a United Aircraft Products wobble pump and separate fuel filter unit in a box. They are pretty old and I was looking for advice on rebuilding or replacing them. A rebuild manual would be very helpful.

Also planning on running a start only battery and no electrical system so an electric pump is out.

I don't need the latest and greatest but just something that gets the job done. I've also got some limited experience with the christen wobble pump and would like to find one but I have no idea what they run used these days?


Any and all advice would be greatly appreciated.

-J
