About a week ago I decided to upgrade my fuel pump to the 255lph. I knew I had a volume issue which is why I did the upgrade. At that point I also installed an adjustable regulator. When I removed the tank and pump I found the old sock had disintegrated. And completely clogged the old pump, surprised the car raj half as good as it did. It would fall on its face over 5-6 pounds of boost. After the pump regulator and filter it was like a new car again. 12-13 pounds of boost by 3-3500 rpm. That lasted about a week and now I'm back down again I changed the fuel filter again checked my fuel pressure which is still good. But I'm lucky to pull 10 psi by 4500 and definitely way less power than last week. Any input would be great.
