Hi, Yesterday I swapped The complete Hard line from the fuel tank to filter to -6an braided, Already have Filter to rail Kit. My static fuel press at idle is 55psi. When start the car with the new line the fuel press was drop to 40psi. fixed to 55PSI again with the regulator.

This is normal after put a bigger line?
