Guys,
            OK,   I got into this discussion late... 
       I am trying to locate a backplate
       fuel pump unit for my O.S.  1.60  FX engine.
       I read the infomation by Tom Koenig from last year, but still need the
       unit contact information.
       Does this unit acutally exist ?
       Maybe someone out there has a unit to sell?
       If not, can you  give me the forward  to this unit ?
       Austrialia?   Sheesh....

When I first heard about people doing this, I thought it was really neat.  
Now, after thinking about it, I can't recommend doing this.  Many engines with 
backplate pumps have problems with the pumps overheating, and vaporlocking or 
deteriorating.  I've seen this on Webras and Mintors, and watched the owners go 
to external Perry pumps.  Having the pump separate keeps its temp closer to 
ambient.  Plus, you can go to almost any hobby shop in the country, and buy a 
Perry pump off the rack for $30, and not worry about having a hard to find 
spare in an emergency.  You can change it out without removing the engine if you 
suspect a problem.  Todays widebody pattern ships have plenty of room in the 
nose, so mounting it is not an issue.  In addition, a separately mounted pump 
makes it much easier to adjust pressure as you are setting it up, and it isn't 
subjected to all of the vibration of the engine.

Just my opinion.
