fuel tank motorhome

[bigdaddy4x4]

I just bought a 1997 Fleetwood pace arrow motorhome with a vortec 454 its been in a storage yard for 6 years I had it towed to my house because it was not running and when I got it home to see why it doesn't run I put batteries in it and could hear the fuel pump running but it was out of gas so I put in 5gallons and tried to start it well when I did a couldn't hear the fuel pump it just quit I checked the fuel pressure it has none so I crawled under this thing thinking it had a 35 gallon tank well it aint no small one its huge any ideals what it would take to drop the tank and replace the fuel pump would help thanks
