i got an upgraded fuel set-up, new sec. rail new lines and new injectors and fpr. it was pre assembled and the fittings were already on there. i just was wondering if this sounds right. it comes in to the fpr, then it goes to the secondary rail then to the primary rail then out to the return line. does it seem mixed up or am i the one thats mixed up?

THe regulator is usually last. I don't know if it will work that way.

It should actually go the complete opposite direction. In the primary to the secondary out the fpr.
