Hello

OK with a modern diesel engine you can get away with about 15% petrol in diesel with no ill effects

as its a 70 litre tank then 1 litre is only 1.5% so you will absolutely fine

If you want to be absolutely sure then I'd say to add a bottle fuel treatment such as this

https://www.amazon.co.uk/Millers-Diesel-Injector-Cleaner-250ml/dp/B0168KHDW8/ref=sr_1_25?s=automotive&ie=UTF8&qid=1476213552&sr=1-25

that will add a does of lubricant into the fuel and help protect the pump seals against any damage from the petrol
