Default fuel tank replacement

How hard is it to remove the Driver side fuel tank on a 98?
I have had issue after issue with my fuel system, and now I have a leak around a bolt on the fuel pump so I guess I'm going to have to replace the DANG TANK!!!
I've already done a search and can't seem to find anything except the right side

can anyone help?

Caution
Provide additional support when a vehicle is on a hoist in the following ways:

Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.
Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.
Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.

Thanks Bryon

That SOUNDS like it is a PITA
Not really sure why you would have to take the muffler off, unless you can't get your arm/hand up to where the cross over tube/s are located.

Anyone done this that can give a "difficulty level with the car on jack stands (as opposed to a rack) and time it takes to complete?

Thanks
