I am thinking that if you fit the petrol pump in place of the diesel pump it will probably work but the pressure is higher and the flow rate possibly higher ? The pump will be started more often than would otherwise be the case leading to it not lasting quite as long but thats not any different than someone fitting a 255 lph Walbro pump in a car that uses 10 lph in normal driving , these things must be switching on and off every few seconds ? I doubt that a higher pressure in tank pump would affect the injection pump as the regulation is done on the high pressure common rail side but would it throw up any unwanted codes or even worse the dreaded 'urgent engine service' warning on the dim ?
