I think the in tank pumps working

In tank pump NOT working is classic of loss of power on hills. Check it for function as laid out in "How to" section. You have to work through things logically. Not just assume. Number four injector also may cause this. Diagnostics may tell you more.

Work your way like this guys are suggesting.
To test map disconnect plug, drive for a few km. Any changes? If No then it`s not working.
In mine it makes a hell of a diference and it takes about 30km to happen...

You talking about the sensor located on the fuel filter? The effect of disconecting should be immediate if it's working.
 
Do the dse have the filter in the tank to ???
Just a gauze filter on the pump pick up. Irellevant, just drop the fuel filter and jump the pump relay to see if it's pumping. Details in Wammers write up in the How To section I think.
