My Ride: 2004 BMW M3 Coupe
I have this problem on my 04 M3. However, no loss of power or stuttering as long as I'm above ~1/4 tank. I checked the cluster info, and it stated that there is plenty of fuel in the driver side tank but the passenger side tank, where the fuel pump is, was empty. So what exactly transfers the fuel from driver side to passenger? The fuel sending unit I presume? Am I right that the fuel sending unit is both a sensor and a small pump?

16116768788 -- this should be all I need right?

ECS calls it just a sensor, is this a pump as well?

Just wanted to double check that I don't also need a fuel pump. Thx guys.
