Ok an update.....

I have reinstalled all of the fuel system components except the mechanical lift pump which is now electric, after all of that I took the time and carefully examined/smell the used engine oil and realized it was not diesel but trans/hydraulic fluid!!!!!!!!

I removed the hydraulic pump again and found the new front seal had a split and was blown out.
Ive replaced the shaft seal and the front and rear 'E' seals inside the pump, now to put it on and try again.

If that doesn't work Im thinking maybe the pressure relief valve? Can this fail and cause over pressure, it seems it can only fail to reduce system pressure?

You did try that.......Now to replace the hydro pump ! Do not adjust the pressure !
