However, it is possible that a clogged fuel filter can seriously damage your fuel pump. If the fuel filter is clogged, it will prevent enough gasoline from reaching the engine and force a higher demand to come from your poor old somewhat unloved fuel pump. This added strain over time causes the pump to become less efficient, reducing its lifespan as a result. Fuel pumps are designed to function under very specific pressure and flow parameters that correspond with industry standards (30-60 psi for most vehicles)—and likewise, the volume of fluid each component is able pump. As the filter becomes clogged, pressure falls and also results in wear & tear on internal items of pump.
The cost to replace a failed fuel pump can run anywhere from $400 on the lower end, up to upwards of 1K depending upon what make and model you drive. The amount you pay for a new pump to do at that price varies; on the low end, Toyota might hit around $500 and (at least in premium marques) Audi or Lexus could require more than 1K. On the other hand, you can replace a fuel filter for $50-$150 which is far cheaper than potentially damaging your amazing car just because of one simple mistake.

Given the above case and that a clogged fuel filter will mean earlier failure of your vehicle, it should be clear why this is critically important in an automotive industry. For instance, a research was done by AAA and they discovered that 10% of the cases of fuel pumps failing entirely were because their filters became clogged or restricted. The filter needs to be attended to in order for this statistic not become an even more, relatively expensive service.
In one of his the interviews, Elon Musk said: One of the toughest things in engineering is to try and design a part that can handle stress when it's outside normal working conditions. Modern vehicle fuel pumps are built to last, but constant use with a restricted filter puts them into an abnormal scenario that goes beyond what the device was designed for. In the long run, this decreases the life of pump causing total failure.
The answer to whether a clogged fuel filter destroy the fuel pump is also clear - it definitely can. The blockage makes the pump work more and that increase of applied power decreases not only efficiency but also wear rate what in general leads to an early death. Prevention measures, such as regular replacement of the fuel filter also helps to protect all parts of the fuel system.
