Hello,

It's been a while since I posted, but I could use some help on this one.

I recently installed a newly painted valve cover and resealed the front timing cover using the Tech Info links posted at the top of the website. Very helpful!

While I had everything apart, I decided to replace the vacuum hose between the head and idle control valve. To do this, I had to remove the cold start fuel injection valve, which needed the top metal hard line to be removed first.

Anyways, I have buttoned everything back up, I reconnected the battery and turned the ignition to position 2 just to get the fuel pumps primed and inspect for leaks before starting the car. I am getting fuel leaking out from the top of the metal hard line that connects to the top of the cold start injector. I attempted to reseal this connection by removing it, cleaning the threads, oiling the threads with a very small amount of grease and retightening the connection with my 12mm wrench while also pushing down on the metal hard line to try to get a good, tight connection between the hard line and the injector.

Are there any tips of tricks to getting this connection resealed? I fear either the injection valve mating surface or the mating surface on the metal line has some kind of bur that is preventing a good seal, but the metal line is really hard to move, and impossible to inspect without removal from the fuel distributor. Open to suggestions if anyone has run into this problem before.

Thank you
