I have a 400 with a jpi 930 in it. 2 different times the fuel pressure went down until i got an alert then back up way high. the guage jumped for about a minute then leveled back out. worked fine the last 30 minutes of the flight. It also has gami injectors and I've noticed a small leak at the number one and 2 cylinders. Just wondered if anyone has seen this before. Was too hot to check wires or sender yet
thanks,
Buddy
