I replaced the head gasket on my 01 xj and lost the bolt holding the hard fuel line to the intake. Does anyone know what size it is? I'm honestly not even sure if it was there at all.

 

The parts diagram for the fuel lines shows a couple of M6 self tapping screws and a stud in one location.

 

I'll get a couple and try that; thanks a bunch, I couldn't find anything on them.

 

Its not a self tapping screw...its the stud one like the standoff on the valve cover or the oil pan but I cant remember if its a 1/4 stud or a 6mm metric. The fuel line clamp goes under the midpoint nut and then the harness with the rubber boot goes onto the remaining stud..I think its metric but will check later

 

All the other screws around there are metric, so I would assume M6.
