I agree the main reason of having a fuel filter is to avoid the the injectors to get clogged with dirt, so it would make sense to have the filter right before the injectors. However I have seen many system that have the filter before the pump.
filter before the pump:
Pressurized filter after the pump:
I will keep looking for more information, but If it is better to have a filter after the pump, I will start looking for a pressure rated filter then. Now the question is, if we use a filter after the pump, where do we put the pressure regulator, I bet the filter will produce some pressure drop so should we put the regulator after the filter? What do you think?
Well actually the last figure kinda answer the question, it looks like the regulator is after the filter.
