I bought a high pressure Walbro 255lph fuel pump for my car the motor will be .20 over,raised compression to 10:5.1,ported head, cams,etc it will be N/A B17 for the time being I may add a little N2O later on if need be. Should I keep the high pressure pump or take it back and get the regular 255lph pump?

You will only need the high pressure version if you’re boosting. IMO, the regular pressure Walbro 255lph is plenty for N/A applications.
