Car getting more and more sluggish fuel pressure low

[ididdy]

I just got through testing my fuel pressure and it ranges between 20 and 30 psi. I tested from the little port on the driver side of the fuel rail. Would this low of pressure be causing the poor response and lack of power? Which parts should I replace first?

Thanks

UPDATE

Replaced fuel filter, re-checked pressure.... still the same, checked for faulty pressure regulator, seems to go up but only up to about thirty when I disconnect the vacuum for the pressure regulator.

UPDATE

Ordered a fuel pump, didn't receive any suggestions here so I went with my instinct and ordered up a 190lph Walbro kit, that should give me adequate fuel pressure right?

Yes it is but whats wrong with buying a stock fuel pump?

I think you made the right decision with walbro.

Very well known ..... EVERYONE uses them.

The Walbro is close to the same price as a stock one and flows much more fuel, you do the math, i did.
