My previous MH was 2001 Residency on a 2000 F53/V10 chassis. I had problems with gas gauge. Dropped the tank to replace it only to find it was working to specs. The ohm readings were correct. I ended up running new wires for the sensor from a connector near the rear of the transmission to the tank to bypass the original faulty wiring.
When I though I was done, I went to start it. It fired up and died right away and won't hit a lick afterwards. Pressure test on the frame rail verified I had no fuel pressure. After dropping the tank again to pull out the fuel pump figuring it had failed, I discovered the Siamese connector on the fuel pump was bad. It had overheated and melted the plastic of the connector so badly, I had to pry it off. I checked the fuel pump with an ohm meter and it checked okay. I cut the connector off the wires and crimped two 1/4" spade connectors on in it's place. Put it all back together and never had any problems over the several more years and 10s of thousands of miles afterwards.
I had read on here back before 2005 of several Ford fuel pumps being replaced (on both the 460 and the V10) to the tune of $800 by shops. After finding my trouble, I wondered how many were just bad connectors instead of faulty pumps. The problem was a bad connection at the spade connector causing the heat that melted the connector and charred the connection. My pump never gave me any problems after redoing the connectors.
I got pretty good at dropping the tank. I found I could remove all the tank hangers except for those at one end and let the tank hing itself down with a floor jack which allowed access to the top of the tank to remove the pump with the level sensor assembly.
Much later, I had to replace the gas line to the generator and needed access to the top of the tank again. This time, I squeezed into the pass-through storage compartment right above the tank and cut a hole in the floor of it right above the tank. Wish I had thought of that to start with instead of dropping the tank. The biggest problem with dropping the tank is the fuel fill connector that goes through the frame. It's hard to get at. I ruin the hose - finding a 1-1/2 fuel hose was a problem - NAPA to the rescue.
