Found one and wondering if any or you would know what it is for? Manual with it was printed in 1966, may have come out of a helicopter? The feloow who put this together is no longer with us, he was a mechanical genious, just check out this operational fuel system. Posting some pics shortly.
Sorry for the poor quality pics, its in an upstairs with poor light.
