Has anyone experience fuel pressure surge? My fuel pressure surges to about 50 PSI for about a couple of seconds when the fuel boost pump is on. It happens almost every time but have found no specific pattern as under what condition it goes up. My engine driven pump runs at about 27 PSI and with the electric pump it goes to about 33 PSI. So was wondering if any one has any inside to this and if it is an issue or just normal with most systems. I have a IO-360-M1B engine and RV7A
Thanks in advance
