I operate an RV7A fitted with a 190 Lycoming Thunderbolt and a Silver Hawk EX 5VA1 Fuel Servo.
Total time is about 80 hours.
This is a new problem.
When parked in the hangar, tanks off, throttle and mixture fully back, fuel drips from the bottom drain of the inlet manifold (sump) immediately aft of the servo.
In the picture I have added, the outlet is in the bottom left hand corner under the red airbox.
Can anybody tell me what is the likely cause please?
