There is a petrol pump at Applecross,
The other thing to do at Applecross is to go into the Applecross Inn for lunch and order a haggis and cheese melt on ciabatta, accompanied by a pint of ale. No need to worry about drink/drive, as the food will fill you up so much you'll need to have a wander around for an hour or so to digest it before you set off again

We'll be up there in the first week of September, fingers crossed for the weather.
