Secondary Fuel rail bolt sizes?

I searched through the archives, and looks through the service manual parts list, I can't find the bolt size for the 2 secondary fuel rail bolts anywhere.

I lost the bolts... I hope I can find some at the local hardware store... does anybody know the size/thread/pitch?

thx a million

I did something similar, ended up bossting a bolt in the UIM. I can't remember the pitch though.. I'll check my recepits and see if I can find anything... BUT, as a good guess, grab a DC/UIM bolt and slowly try to screw it in, IIRC they are the same. If it hangs, DO NOT FORCE IT!!. Its just a guess! Anyhow, if it goes in ok, take the bolt to NAPA or the hardware store and find a smart looking person, tell them its metric and you need a handful of them.


Why a handful? If you lost fuel rail bolts, you'll lose more in the future.

EDIT: the only thing I can find in my reciepts is 10x1.25, but I can't remember what that went to.

They are 12mm heads, which means it's a 8mm diameter.
It's most likely a 8mm x 1.25?
I can't tell you lengths, cause they are two different sizes.

I do remember them being a bit smaller, and they are 12mm heads... I'm thinking Ted got it right first try (no suprise there)
