Car at idle heard a very small pop and car cut out, will not fire up just turns over and diesel pouring from out back over tank and filter housing.
Sounds like the pop was a fuel line coming off. When you say diesel is pouring over the tank and filter housing do you mean the fuel tank? Where exactly is the fuel leak?
It's hard to say where the leak is as running off the fuel tank.
I think the fuel filter housing has failed which is fitted above the fuel tank... it seems to be a relatively common problem.
