Fixed my typing on my PC. Sorry. My fingers and cellphone touchpad don't mix well. Doh !

So the issue all a long was a misplaced vacuum line ?

Hi All,
Seems that all has been resolved. Boat is now getting on plane. Fuel pressure was indeed causing the issue of loss of power.
Vacuum tubes are in correct order and 30psi is constant on all rpm ranges.

I thank all of you for your input in solving this issue.

Many Thanks
