Anyone know the correct size cap that's needed to plug the hole that the cold start injector hooks into (back side, driver's side). My CS injector has been leaking so time to plug it up, and I ain't about the buy the $70 kit.

Thanks fellas

 

bump, thanks

 

Couldn't you take it off and bring it to a parts store and have them match it up?

 

If I didn't drive it every day and could park it awhile sure.

There's gotta be someone with a fuel rail off their car already.

Guess I'll have no choice but too...

 

Cool found it on a digitalcorvettes.com

It's a -8AN port plug. Can snag it at a plumbing store or Earl's online for a few bucks.

No way in heck I'd pay the $30 or $65 that some companies charge, what a bunch of bs!

 

Old thread but for any who read this, IT'S NOT an 8an port plug! I found this thread and another so I bought a 8an port plug and it's larger. So I welded mine, but then I messed up the hard to find o-ring.

 

Must be different sizes over the years/models. The plug worked for me, my rail is off a C4 Vette.

 

If yours isn't -8 AN, what is it?

 

So is mine an 86, I'll check the rail off my 85 TA I still have. I already checked the port plug and it's 8an, I have a cap that size and several other fittings so I know it's correct.


edit: I would think if there was different sizes, the people who sell plug kits would sell two and say something like make sure you get the right one.

 

Even in this ebay add you can see the 8an end is larger http://www.ebay.com/itm/Chevy-TPI-SBC-Cold-Start-9th-Injector-6-8-AN-Adapter-Runner-Plug-Kit-/311421501359?_trksid=p2141725.m3641.l6368
