Jay, i know the pressure is regulated by the pressure regulator, i may look thick but im actually not
I'm sooooooo sure the pumps different. Its the fact of how much fuel the pump can deliver under full load, thats when it makes the difference, same pressure, but faster consumption!!!!
right, taken from auto data itself, these are the details for the pumps on the fiestas.
xr2i 1.6
delivery pressue 5.0 bar
regulated pressure with vac 2.3-2.5 bar
xr2i 1.8 zetec
delivery pressue 3.0 bar min
regulated pressure with vac 2.5-2.9 bar
FRST
delivery pressue 3.0 bar min
regulated pressure with vac 2.9-3.1 bar
all i could get on the RS1800 was regualted pressuer WITHOUT vac
2.5-2.9 bar
so you see a xr2i pump is fine for use, and really you shouldnt need to adjust the regulator just by changing the pump.
maybe the FRST uprated pump is a 2I pump
