MGB tanks rust out at the top as they are mounted flat to the boot (trunk) floor with a small gap that gathers road dirt. So the first sign that there are problems is the smell of fuel but no leaks!
I had a little Hillmam Imp many years ago, it would run just fine until it got to 40 mph, then it would splutter and lose power, slow down and it would run good again. Eventually I took the fuel tank off and cleaned it out to find a small chunk of filler cap rubber seal in the tank - someone previously had replaced a broken seal but didn't retrieve the broken bit out of the tank.
So this chunk of rubber was floating around in the bottom of the tank and at 40 mph the suction of the pump was enough to pull it over the exit pipe and cut off the fuel.
The Imp was a brilliant little car, rear engined. The engine was derived from a coventry climax fire pump engine, all aluminium 4 cylinder 875cc 39 bhp! The engine was canted over at 45 degrees to fit under the rear of the car with its transaxle forward of it.
This made changing the 6" clutch dead easy (needed to be as they only lasted 10,000 miles or so) I once did it in the works car park over a lunchtime - support the engine on a jack, undo the bellhousing bolts and wiring, undo 8 bolts on the rear crossmember and push the car away leaving the engine on the jack! Change the clutch and reverse the process...
