1995 BMW 318Tds Fuel Starvation Problem

Fuel returning to the left side of the tank is not being transfered to the right side of the tank quickly enough causing the pickup pump in the right side of the tank to draw air and create a fuel starvation problem. Engine shuts off as a result, this happens even if there are three gallons or so in the tank.
I have checked everything, pump, pipes etc and cannot find any faults,
However I have been advised by BMW that there should be a valve situated in the external fuel transfer pipe which runs over the top of the tank from left to right which may be faulty. I have removed both the left and right inspection plates under the rear seat and the ends of the pipe are visible but not the valve. Is anybody aware of the existence of this valve and is it accessed by completely removing the fuel transfer pipe.
Help will be appreciate.
Regards, Bob.

Sorry this is not a solution. Just to say I own a 1997 318tds which only starts on the button if the tank is at least half full. This was looked at professionally shortly after i bought the car 3 years ago.( I did wonder why it was sold to me with such a full tank). I was told it would need the fuel tank replacing. Bearing in mind the value of the car & the fact the owner is now too geriatric to do major repairs, I just make sure it is always half-full, and live with it.. This could be your problem. BMWs chap said it was logged on their system as a known but unusual fault.

My car stoped running as if it were running out of gas but i have gas in it now it will only crank but not start it is a 92 BMW 320i


Has the fuel filter ever been replaced? Instructions are here. http://www.frontiernet.net/~papi/Filter.html
This car has two gas tanks, one on either side of the spare. The fuel pump that delivers fuel to the engine is on the right-hand side. When the left tank is less than half full, it requires a transfer pump to move the rest of the fuel over to the tank with the fuel delivery pump.
Those transfer pumps sometimes fail, or can simply come loose. When that happens, the car 'runs out of gas' though it still technically is one quarter full of fuel. It cannot access the rest of its fuel. This happened on my bosses '03 325 a few months ago.
If this is the problem, you can be sure to keep it more than half full of fuel until you can get it in to get it fixed.

How do i change a 2004 Lincoln LS fuel pump?


Hi. here's how to change the fuel pump. The actual electric fuel pump is in the tank on the right side. The tank is directly below the rear seat. If you remove the seat bottom you will find a 6 inch or so cover. Under the cover there is a plastic, threaded collar that locks the fuel pump into the tank. The driver's side also has a pump, but it works only my venturi effect from the electric pump on the other side. This pump is used to equalize the fuel level from left to right. The drive shaft tunnel prevents all but the very top of the tank from communicating left to right.
