Has anyone added a fuel filter after the fuel pump in addition to pre pump filter?
I know the Spica set up had this, but it was bowl set up and the Spica had a lower fuel pressure than the F.I. in the S4. Would a filter adverserly lower the fuel pressure too much? Thanks in advance for any input?

There already is a fuel filter after the fuel pump. Big can thing in front of the pump. It's there to project the injectors.

The only pre-tank pump is the sock attached to the in-tank fuel pump.
