<DIV>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.</DIV>

<DIV>Just my opinion.</DIV></DIV>
