What is the voltage at the generator fuel pump when it's trying to pump?
Are you trying to empty the fuel tank so you can drop it? If so use the in tank pump. You should or could have a schraeder type valve on the engine where you can remove the stem and cram a hose on the fitting. Then jump the fuel pump relay and pump into fuel jugs. You will be moving fuel and working with electrical stuff that can arc. Be careful. Dont work on stuff like this with it parked indoors if you can help it and park away from your building. Fires happen all the time from stuff like this and just wanted to mention it.
The are various electric fuel pumps for small engines generators etc, you need to have the correct one for your generator. Someone could put the wrong pump on it and then it gets replaced with another wrong part number. From there if all the lines are good there should be no reason for it to not pump. The slightest air leak on the suction side can mess these things up. A leak on the pressure side can burn you to the ground. Be sure everything is top notch. Protect any wires and fuel lines from abrasion. Use old tire tube, heater hose or whatever to protect things.
