Cool, thanks man. I was asking 'cause I was unable to get the cap to seat tightly against the plate w/ the fuel lines and stuff. It's just a hair too loose and hitting it w/ a screw driver manages to ream off the knurled edges so I don;t wann do that.

Reason I was wondering is because my car still stutters when not under boost and I am just grasping at straws. I'm to the point to taking it to a shop and paying someone to go over the whole thing to figure it out.
