Hi, I have a 2008 Saab 93 1.9Tid since new. There is a problem on it that the dealer cant seem to fix. When I drive up a long incline at 100 - 120 km/h the there is a loss of power and the engine starts vibrating, it happens intermitently and comes right when the road levels out again. Please help.

It is more apparent when the tank is half or below, the fuel pump was replaced at the last service, but the fault is still there. A friend told me there are two pumps, one on the engine and one at the tank itself, is this so?

Yes there is a high pressure pump affixed to the engine, did u do a fuel pressure test while driving & looking at the tester gauge pressure, if not get that done, also replace fuel filter, good luck.
