Was driving pretty hard up one of our mountain roads with the tank around 1/4 full. Got almost to the top with a hard sweeping right turn and the car started bucking. Felt like hitting fuel cut. The car was bucking and jerking at about 5k in 4th gear. Slowed down to about 3k and gave it gas again and it did it again. slowed down and limped it to the top and the fuel light came on with DTE saying 0. Thought I was out of gas and got to the gas station at the bottom but only filled up to 14 gallons. Meaning I still had the quarter tank like I thought I did. Anyone had this happen before and is this normal? I could only guess that all the gas had moved to the left tank in the sweeping right turn but I didnt think that would happen with all the baffles in the tank?

 

Normal, our fuel pickup is a crap design. With aero and wide sticky rubber I start to fuel starve with 11 to 12 gallons left.

 

Could this have anything to do with the 350z’s dual fuel sensor system. I’ve noticed a problem in my 2003 that is a discrepancy between the Z’s gas gauge and the digital DTE reading. The problem is inconsistent in my case.

Also... I do notice the fuel-starving that terrasmak describes.

The dual full sensor design is what causes the error on the gauge and DTE gauge. Once the car sits back on normal ground it will slowly go back to normal. The big problem with the car, the fuel tank is basically 2x10 gallon tanks with a small link between them.

 

Yea, its stupid. My mom's mercedes has the same type of fuel tank design, but the big difference is there's a motive flow pump located with the sending unit in line with the electric fuel pump. Gonna try to duplicate the scenario with a full tank and see if it still does it. Hopefully its that and not something worse.
