Diesel presuure seal leak, air in filter, no start

I read the forum on leaky seals on top of the injection pump. Would these leaks lead to air in the filter and thereby no pressure to the injectors? If I park with the nose down by 20 cm from the rear, the car starts every time. If I park level or God forbid the nose up, the car will not start unless I bleed the fuel system. My o rings are showing some weepage, but that is the only leak I see. The car is a 1987 station wagon in A-1 shape. The engine has 147,000 and has used bio for two years.
