I just installed 4 new bolts in my 2004 rubicon's fuel rail. The old fasteners were in fine shape, but 2 were missing from before I took ownership of the jeep. I noticed the front fastener was actually a stud, and in some pictures of other TJ's I observed that the rearmost fastener was also a stud. In none of these pictures or on my own jeep do I see anything at all mounted to these studs. Maybe when the 4.0 engine was used in other vehicles there was something mounted to them. Does anybody know the purpose of the studs mounting the fuel rail?
