i only had 9 volts to the fuel pump before i did mine now ive got over 14V
renew the earth aswell.Also its worth renewing the alternator - battery cable, this gains resistance with age and heat from around the turbo area, i agian gained 1V at the battery from doing this....in turn gained that 1V at the fuel pump!

And whilst you are at it, think about replacing the fuseable wire ends on the cables next to the battery (presuming they are also no the 4x4 like they are on the 2WD. I gained a couple of volts across everything when I did this.
