Fuel stockpiles, Canada, and Atlantic tanker risk

Would fuel shortages prevent Britain from operating the much larger escort fleet in the mass-production scenario?

Protected tanker routes and existing fuel reserves would support the extra escorts, although production might still struggle to match demand.

A larger escort fleet would not automatically exhaust Britain's fuel supply in this scenario. Fuel arriving from Canada gives escorts an opportunity to replenish at that end of the Atlantic route. Protecting tankers removes the losses that otherwise interrupt those deliveries. Large reserves built in Britain and across the empire from the 1910s onward also support sustained operations. The remaining concern is whether fuel production could keep pace with the enlarged fleet's demand.
