Fuel return valve



vin 4JGBB2FB6AA593877
I need to know is there a fuel control valve just before the fuel tank
I saw a video for a car in which this valve stuck open which make several tries to start the vehicle
so , if the ml has the same valve I need to know it's location and part no. pls
thanks



I have code P0087 for the past year till now
the car works good , when cold start at first try , when engine hot it takes about 5 second to start and some time at second try
I did change new injectors
new fuel filter
new tank fuel pump
😶
the video in the link below
Thanks a lot and have nice week end
