Thanks for the update. We'll be interested in how it does at WOT. I'd bet you'll be fine.

I have yet to source the rebuild kit part number C7AZ-9349-A but I did find a very helpful website that has a step by step rebuild with pics here http://www.428cobrajet.org/how-to-fuel-pump.html

Definitely needs more fuel than my HP525SC motors. The mechanical pump seems to be fine for my application. Currently my fuel pumps are as they came from Mercury. I haven't tried the rebuild kit yet. (I found that the erratic pressure reading I was getting on one of the motors was cuased by vibration. I had a mechanical test guage connected to the hard fuel lines at the carb. One cylinder was not firing!)
Clearly from what you describe there is not enough fuel flow at WOT.
