As always the internet's varied opinions on everything has brang me back here to start a thread..

I have a Walbro 255 fuel pump, pushing fuel through a focus 1.8 standard rail and standard regulator with focus RS injectors.

Someone once told me this regulator would be fine, now i'm hearing things like 'the regulator won't flow enough for the pump' and 'it needs to be rising rite otherwise it won't fuel properly under boost'

Help?
