Winnebago New Zealand 1975 Winnebago Indian Motorhome Is Not Getting Gas To The Fuel Pump?

1975 winnebago indian motorhome is not getting gas to the fuel pump? - winnebago new zealand

I filled the tank and fuel pump changed, and filters. The problem is that there is no gas for the fuel pump, but also ran a week ago. Do I want the tank to find out what is the problem? For tanks sit high and is difficult to see anything (which is where the lines go). Please help.
