Hi Jeff,

The additional volume will not affect fuel pressure. If you were
restricting the flow of fuel, pressure would go up; this sometimes
happens with a bad fuel pressure regulator. The engine will run rich as
a result. But simply increasing the volume of fuel upstream of the FPR
will not affect pressure.

Happy Trails,
