One typical example of a restricted fuel filter is a vehicle that cuts out or loses power driving up an incline, such as a bridge. Under load, fuel demand increases and a clogged fuel filter reduces the needed flow. As the fuel filter gets dirty, the fuel pump works much harder. This is why a restricted filter will damage the fuel pump.

A misfire at idle or a vehicle that is hard to start is NOT normally a symptom of a bad fuel filter. Fuel requirements at an idle or startup are low. Even a badly restricted filter can supply adequate fuel under low load conditions. As the need for fuel flow increases, the restricted filter will reveal itself. This is why we notice bad fuel filters on acceleration and when climbing an incline.
