E39 525TDS Keep runnng out of diesel
concerns my 1997 525TDS
When the tank is on 30 liters or less, when turning on a corner, I keep sucking air into the system. When driving straight, it's the same when on less diesel, but still the same. Result is running out of diesel, so stalling, and starting problems when there's less then 30liters diesel in it.
It's obvious it's sucking air, because there are bubles in the transparant fuelline behind the dieselfilter, unless I've just filled it completely. There's bubles in the line even when there's more then 50 or so litres left. So far I've changed replaced the sucktionpump, checked for worn seals or leaks in the diesellines, but couldn't find anything.
Is there any abvious faults I'm missing or forgetting?
Would be very greatfull to sort this out, refilling after every 450km's is a pain in the...
