Default Need to know thread size...

I need to block off the the 9th incector port on the back of the fuel rail. Does anyone happen to know the thread info for that? Or atleast tell me if it's pipe, metric etc. Something to get me started Thanks

If memory serves, it's metric thread. I believe the size of the pipe nut is 18mm, but I wouldn't swear to it (I was reconnecting it at 4am, so the size has slipped my mind :rolleyes: )

If you feel like spending some $, either Accel or TPIS have a block-off plate for this. As I recall, it was a real expensive plug. :rolleyes:

thanks guys. I figured it would be metric seeing as how I used a 19MM wrench to get it off. Now where do I find a metric cap? :banghead:

I bought a pile a while back because a bunch of forum members said they wanted them, then only 1 or 2 people actually bought them, so I've still got some. If you're interrested, send me an email (iroc85@sover.net - my regular email is temporarily down while we change servers). I'm using one on my IROC with a little teflon paste, and it hasn't leaked a drop.
