fuel starvation???

[NOVA WHITE 1.8]

i recently changed my fuel rail on c20xe,and now it runs like its being starved and needs more revs if not will cut out??its not the afm,changed back to original fuel rail,any ideas???

[just vaux trev]

is it ok on the original fuel rail? if so maybe fpr ( fuel pressure regulator ) on the rail.

It certainly sounds like the FPR if it runs OK on the old rail.

Out of intrest, why change the fuel rail if its running OK?
