I laredy replaced the heater and fuse and was referring to carrying an extra fuse and disconnecting the heating element if it happened again in a remote desert so I could limp the 50 miles to a town if needed.no. you should just replace the fuel bowl heater element with the international one or you will be blowing fueses back to back.
were is the fuel heater located
