My 57 Honda Civic recently came to a halt and had to be recovered. Roadside diagnosis was fuel pump problem. My local Honda garage finally diagnosed that the high pressure pump is damaged and their expert suggested that it'd been destroyed by contaminated diesel.

They also advised that the fuel injectors should be replaced as they're likely damaged at the same time.

I've had the car three years and never mis-fueled it and had done well over 250 miles on it's most recent tank.

Faced with a massive repair bill I contacted my insurance company but was told that they wouldn't help as there was no one to claim against.

Do I have and options other than to pay the bill myself?
