I sure hope no FLAPS is suggesting you use coolant hose for fuel line !!

gasoline eats rubber.
fuel hose is neoprene usually.
Eventually rubber will get into the fuel pump etc. if coolant hose is used.

ask for 7/16th's fuel hose and see if that's about right.
7/16ths if very close to 11mm...
You can use the two wrench sizes interchangeably.
