      I have a Holley 255L/hour in my GTO and I have never had any issues. I have a pressure gauge mounted in the car and I have never seen any dips in pressure, even at WOT. I have 500RWHP, so you should have no issues.

      Walbro Pump

      I believe the Holley pump is made by Walbro. The 255 L/hour in-tank should be more than adequate. I had Rock Valley install a Walbro pump in a reproduction 67 tank and it works great. :icon996:
