Holley fuel pressure regulator Summit fuel pressure gauge - at-speed photos
Holley regulator and gauge, not calibrated, basically identical to the setup pictured. Both sat while car was stored.
Have run two different pumps to cross check. First a US made pump, looks like a small bosch, worked fine with prev. engine, sat while car was stored, I susepct it was still OK. Second just installed, a brand new carter. I suspect I wasted some cash on this.
Pump and filter are installed in front trunk, beside spare, big (new) fuel filter first, then pump. Regulator is in engine bay, below battery tray.
Dat's it.....
