How exactly do I take out the gas tank?

[In The Ten Ring]

Moderators: thank you so much for allowing me on. I figured it would happen eventually but I am very happy now!

I have a 1972 Custon 10 Stepside that my dad bought new off the lot in 1971 for $2300.00. It has the wheel on the side and a 3 speed manual on the column, 250 straight 6 engine, and single barrel carb. I've messed up and let it sit for 7 years in my garage but honestly, it wasn't running right then. Dad had let it sit 10 years prior to that in his garage and never got rid of the old gasoline. It would stall out in the middle of the road.

Last week I siphoned out the old gas from the tank, changed the oil and filter, and drained the radiator, replacing that with distilled water. My next goal is to remove the seat and gas tank and have the tank cleaned, carb rebuilt, and blow out my fuel lines with compressed air.

How exactly do I remove the gas tank nozzle from where it sticks out the side of the truck?

Thanks!
