Hi all was after some help. i have a mk3 2.5 v6 zetec s and the fuel pump failed so i replaced it and was told the 1.8 2.0 and 2.5 were all the same but has proven they are not as the car looses power and cut out. So i was wondering as i can get a hold off a used 2.5 one would a 3.0 st220 one be ok?

Thanks Sean
