I find it hard to believe your pressure is that high. Unless there is blockage of the return line from the primary pressure regulater or the regulater itself is stuck there is no reason for it. Maybe your gauge is out of calibration. The proper place to check fuel pressure is the bolt on the top center of the fuel distributer in line to the control pressure regulater on the valve cover. Max pressure is to be no more that 5.5 bar or 14.5 x 5.5 or about 80 psi. With such high pressures at start it is all going to the cold start valve. Assume the primary regulater is stuck. Try to remove it and clean it making sure everything is clean and moves easily. It is adjustable and should be set between 5.1 - 5.3 bar. This could have happened overnight by just a piece of dirt lodging in the regulater causing it to stick. The primary contol pressure regulater is on the side of the fuel mixture unit. The control pressure regulater is on the valve cover. The primary control pressure regulater is the one that contols system pressure and is the one that is either stuck or has the bolcked return line.
