Hi there, I have a 2008 g37. I unfortunately keep on having an issue. I dont have gas and i dont mean it by mpg i mean my gauge reads empty but my passenger side where the main fuel pump is, that side is almost full. While the driver side is almost empty. Now i dont have any issues yet im able to drive for 10 miles or more but thats the most ive done since im afraid i might run out of gas in the middle of nowhere. Now i did find a similar post on the g35 forums about it having to do with something called a “venturi” but im not sure what that is exactly. As well as how both sides of the tank have to be equalized but ig mine isnt.
