Thanks to both you guys for the input.
Well, we first tried siphoning from the return one inlet on the sender, then the fuel outlet from the sender.
Nothing.
We tried turning the Key and using the pump and only got spurts while cycling the key on/off.
So we tried what ajakeski said.
Took the right rear shock out.
Removed the 3/16” vapor hose at the metal pipe.
Removed the 5/16” fuel line at the sender.
Removed the 1/4” return line at the sender.
Supported the tank with a floor jack and plywood to support the tank.
Took the fuel cap off and removed the 3 screws holding the filler tube to the quarter panel.
Loosened the tank straps using a 1/4” drive 13mm deep socket, short extension and universal joint.
Dropped the pan several inches.
Turned the filler tube counter clockwise, then dropped it down, and out.
As it turned out, there was only 7 gallons in the tank and no gas spilled out.
Removed the tank straps.
Lowered the floor jack and slid the tank down to the rear and out.
Notes:
Stabil really works well.
Permatex makes a gasket sealer specifically for gas and all other harsh fluids.
I used it to seal the grommet at the top of the tank and the donut on the rear where the filler tube goes in.
