I've taken on the task of getting a neighbors Kawasaki KLR running after a 4or 5 year sleep. I know, its not Brit but it's still s nice bike. The carb and tank are gummed up with very old gas and Marvel Mystery oil. He always ran non ethanol fuel so there is no rust, but whats in the tank is like tar and smelled like the old gas smell I remembered back in the good old days of leaded premium pump gas. I'm thinking that a good soak and rinse with dry gas (alcohol) will melt/loosen/dissolve the mung in the tank maybe? The carb is coming clean with a soak in Hydro Seal but thats not practical for the tank.

Acetone and drywall screws. Shaken, not stirred.

When it looks perfectly clean, add fuel and start motor. You may find vibration has loosened even more hardened fuel and has clogged the taps. Rinse and repeat...

Sorry, when I wrote my comment I didn’t feel like going out to the garage whistle.

PPG DX520 but that was years ago. Might now be SX520. I haven’t purchased any in a while. I also use it to remove rust from small hardware bits, nuts, bolts, etc. I soak them in a glass jar. You have to monitor the process. The stuff is pretty aggressive. It makes bubbles when working. When done I screw the cap on and save it until next time. Beware of sticker shock - $35 for a quart!

SEM makes a similar product called Rust Mort. I've also used Evap-O-Rust for the same thing.
As a followup, I gave the tank back to the bikes owner and told him to have a go at it. He used acetone to get the sludge out then did the hand full of screws and shake trick. Worked fine.

Pardon me if I'm stating the obvious, but remove the petcock(s) before cleaning the tank. I know, it's a PITA because then you have to plug the hole(s), but you don't want to destroy screen filters which may be on the petcocks.
