The Campus petrol station on the Waterford road outside New Ross has a 24hr diesel pump operated by either credit or debit card. Very handy if you're running low late at night. They don't mind the occasional camper staying overnight so long as it doesn't become a nightly event. At times truckers park there for the night. They have a very good deli counter if you want to stock up on a good breakfast before heading off. Cross over the Bridge in New Ross on the N25 heading for Waterford and you'll find it on the left hand side about 1km out of town. LOC8 code Y6Y-51-LM8.
