If it's like my M900 (i.e.) tank, then the pump is just held in a spring loaded clip and so pulls out easily and IIRC the power cable is a simple 2 pin plug though there maybe a simple lock/clip mechanism, I can't remember?

Best to undo the hoses and remove the whole assembly, like this;

But it is a job to get at due to the small opening and tight angle so expect scuffed wrists.

Much better the system used in 916 etc. where a removable plate is fitted to the underside of the tank and the whole assembly simply pulls out.

I've found that you need much more hand penetration to get the pump out of the clip than to get the connector off the top and more still to get the pump clipped back in place properly.
I'd leave the pump alone and just tug on the connector.
Maybe you could get further in with a bit of Vaseline?
Or if your hands are really too big you could wait outside the school gates with a pot of Vaseline and be ready with the line "Do you fancy earning a fiver sonny?"
