i have a friend who has an aem fuel rail on his b18b and the bolt on the top of the fuel rail right near the FPR is leaking gas through it. im not sure what the bolt is for but if he were to just tighten it would it stop leaking. i just looked at it briefly so this may sound like a newb question. what is that screw for anyways? thanks for all your help

 

Bleed off the fuel pressure, remove bolt, use a bolt dressing compound like lock-tite or teflon tape (be careful with the latter as you don't want that to go into your valves...I've never had trouble using it), reinstall bolt.

It's not a big deal and I'm sure you'll be able to fix it in about two minutes once you have the proper stuff .

 

i belive that is for nitrous
