Default cold start fitting size

Alright, this may be closer to topic than my previous super ram thread, now that I've figured out what I need. Does anyone know the size of the fitting at the back of the fuel rails that goes to the ninth injector. I want to block this off, and I don't think I need a kit to do it. Just a bolt and a washer. I can cut down the bolt, so i'm just interested in diameter and thread.

Thanks
Chris

I'm not sure you could use a bolt...It's metric thread and has an O-Ring groove in it..you'd probably be better buying the plug kit from Accel or I think you can buy the plug only from Street & Performance...In the past I've also welded the hole in the stock cold start fitting and used it.

I could weld it, but I may use my old TPI on my truck, so the less stuff I have to buy later, the better.

Would I even use the o-ring, or can I just take that out and use a normal bolt. Everyone I've talked to that got one of the block off kits said it looked just like a normal bolt, but stubby, and had a gasket with it.

Metric isn't a problem, since most of the hardware stores around here carry a good selection of metric bolts.

Sure, that might work...I'm not sure what the tread is but, I'm sure you could call the dealer and find that out.

I broke down and bought it from these guys:

$5 plus shipping and they'd overnight it.
Thanks for the help, guys.
