Diesel pump problem! Metal filings in diesel! :(?
My car is in the garage at the minute due to a diesel pump failure. My mechanic tells me that the pump has disintegrated possibly due to bad quality fuel. He says that this has caused my fuel to be filled with metal filings from my disintegrating pump and is right through my fuel system. He says that I need to replace my entire fuel system even including my tank, which will cost a fortune! He says he will bench test my injectors one by one to see if some of them might be salvageable. However, another mechanic advised me that he wouldn't go to that expense, and would just replace the pump, flush out the system as best you can, maybe test the injectors, and put a big magnet in the tank to catch any remaining filings and leave it there. To be fair, the second mechanic didn't examine the car for himself. Which is the best advise?

See the video and the comments for a discussion of this issue (although the focus of the video is that sort of damage caused by gasoline). The upshot is you can do the whole system and not worry except for how to pay for it, or you can do the minimum and take your chances. The biggest concern is one of those flakes will jam an injector open and the engine will only last a few seconds after that.

Go with the second mechanic however I question the need for a magnet in the tank. The fuel system is pressurized so fuel should not back flow to the tank. Just make sure you have a good fuel filter between the tank and the pump.

Go with what the second mechanic said, the first one wants the easy way out. no need to replace the fuel tank when it can be flushed out. and the fuel system too.

The 2nd mechanic is giving the honest answer. the 1st guy is only trying to ripe you off. there is no need to replace the whole fuel system or even mess with the injectors. even if any partical got into the fuel line, there is a fuel filter somewhere along the fuel line that will stop it from getting anywhere near the injectors.
