I would like to know how the conclusion was reached that the fuel pump was responsible for the fire. Then I'd like to know how a fuel pump can be responsible for a fire, considering it's a piston pushing fuel so you need a source of ignition which is likely to be outside the fuel pump. Then I would like to know, if the above conditions are satisfied, how an Autotech specifically increased the likelihood of causing said fire.
....You would have to speak to people very much more expert than myself in investigating the causes of fires, whether automobile and/or otherwise. My understanding is that there was no doubt.
However, if as you report, there has also "been a case of a catastrophic engine failure in the US on a car with an APR pump with no warning", then as to be expected with even OEM fuel pumps, there is risk. OEM components are
not devoid of any risk.
The wise man minimises the risks. That's why I suggested in my earlier post either fitting brand new Autotech internals in a brand new OEM pump or buying an APR pump (which I personally chose to do as it gives me far greater peace of mind). Simples
The Autotech vs APR debate will never be resolved because we each naturally tend to favour the individual choice we made.
I have asked this before, but hypothetically if the Autotech and APR pumps each cost
exactly the same, which would you buy?
