Hi, This topic has been discussed in detail with many guys and companies involved on another forum, and no solution has been found yet. The company that rebuilt the ones for Ford was located but they have stopped production and have no parts left from what I have understood. If any positive news will pop up, I'll keep you posted.

I have a rebuilt fuel pump with the button on top for an '65-early '66 small block. If interested, email me at 1stnow@msn.com.
