The factor FPR is the bottleneck, so if you remove that you have to add an FPR. Technically the factory setup is a return as well, the fuel being returned just never leaves the tank.

So why take the chance not having a good filter and clogging up an injector or 2 thereby damaging the engine.
The factory FPR has a filter in it.
