as everyone has said
petrol fucks the pump first, when it happnens at work we ALSO have to change the rails pipes when we clean the system out,,, then the injectors will fuck up

reconed pumps are 1000 quid from ford but as said they need programing same as the injectors will also so thats a extra 90 quid plus vat onto of the other labour charges

the high presure ( more than the old ones too) diesels dont EVER use petrol to wash the tank out
