OMG
It terrifies me to think that you are driving this car. I don’t like to criticize other peoples cars or what they do to them but this is a fire waiting to happen and no insurance company would pay out. It would also fail any vehicle inspection and rightly so.
A new pump assembly is unbelievably expensive but surely it is cheaper than a new car.
I am really sorry if I have offended you but you have my deepest sympathy if the last owner did this to your car. I hope you manage to get it sorted before something horrible happens.
