This fuel rail was the original on my d15b7 but will work on others. I fully polished it (360degrees) and had it on my car maybe a week. I have since replaced w/another set up. It may have been hit w/a wrench or dropped? either way it is up for sale and works completely fine.
$30shipped comes w/regulator and nut.
You can see here the 3 spots on the left side of the rail:
