I didnt want to highjack the other fuel pump thread but my question is,will the stock pump send enough pressure for the HO 19lb injectors? Or is that all controlled by the regulator on the rail. If so,should I change my regulator since I used my lopo rail and regulator?

The stock pump should be OK, and the regulator controls the pressure. All ford injectors use the same pressure, and the HO and lopo regulator are the same.
And regardless, it's the volume, not the pressure you need to worry about.Builder/Owner of Badass Panther Wagons

My pump is stock, and until a few miles ago it was the stock 250,000 mile old pump doing just fine. (Turned out that replacing it was useless as it was not the problem.)

Near stock HO should be fine if the fuel pump isn't already dying, but if you build a decently more powerful engine that uses more fuel then an HO, you may need to upgrade. Stock HO isn't a problem. Mine is running on the original 153k mile pump and its doing OK.86 Lincoln Town Car (Galactica).
