How to access water tank in 1993 Eurovan

[roadtripping]

Recently purchased 1993 Eurovan, did not come with owners manual so have many questions. The water pump in the water tank has come unconnected to tubing that moves the water to the sink. How do you access the water pump in the tank? Also does anyone have a owners manual that I could borrow to answer some of my questions, Amazon doesn't have the manual in stock.

Thanks so much.

Is it a Westfailia or Winnebago? On the Westfailia the cover comes off with four bolts (front side side back) and there is a round cleanout port on top. I admit I have never tried to get in there to acccess the pump myself.
