Well, got my fuel rail and my black accufab doesnt fit. The widest part of it hits the rail when you try to mount it. It looks like it was ground "rounded" in the area but then it stops. If the grinding went all the way up the regulator wouldnt have hit. I just took my angle grinder and ground it off to give a little more space, now we are all good. Also had to put one washer on each side with the spacers as the nut on the regulator was gouging into the hole. She looks all good now. Can hardly tell I messed with it.
