940 945 can't pump all fuel

[sekokupu]

945 '95 B230FK / AW71L With single pump system.

Small problem with my 940, it has 75l (~20 gallon) tank, and I was driving up on small hill and I was "out" of fuel, even I had ~30l (~8 gallon) gas in tank. When I got my car on flat surface, it started again.

I replaced fuel pump about nine months ago, and that pump is still working fine. So why it can't get that fuel from bottom of the tank?

it is possible that the feed hose on the in-tank pump is broken.

That hose between pump and top of the fuel sender unit is in good condition. And that filter sock is new.
