does adding a high flow fuel pump alone makes the fuel pressure at the rail higher cause i felt the tention bfore and after the fuel pump and it seems to be quiet high after it passes thru the inline pump compaired to b4 it

 

I added a walbro 255lph intank (not inline) and my fuel pressures went from 38 psi stock to 65 psi, so i had to drill out the stock fpr and that brought it down a bit
