Car Down: Leaking Cold Start Injector Line (From Fuel Distributor to Cold Start Inj.)

[Rahulio1989300E]

Hello,

Today, my roommate and I took on the job of replacing the Idle Control Valve vacuum hose that runs between the engine and the left connection point of the ICV when facing the car from the front of the car.

We pulled off the air cleaner, loosened the wiring harness cradle, removed the ICV, removing the metal fuel line that goes from the fuel distributor to the top of the cold start injector, removed the cold start injector, slid off the old hose which was very tough and not pliable anymore. Then we reassembled in reverse order but did not replace the air cleaner assembly so that we could check for any leaks from the fuel lines first.

Sure enough, just by moving the key to position 2 to prime the fuel pumps, a little bit of fuel dribbled out of the point where the metal fuel line threads onto the cold start injector valve. We tried removing the cleaning this line and the rounded ball heads 4 times, tried oiling the threads with parafin oil since the injector side threads seemed to be a bit gritty.

I cannot drive the car since it is leaking fuel.

We did not want to go overboard with tightening them as we did not want to strip or crack the metal lines. Fuel is only leaking from the injector side, not from where the other end of the line connects to the fuel distributor.

Is there any trick to getting a solid seal? We kept these areas as clean as we could and wrapped the ends with new saran wrap to prevent dirt and dust from gunking up the threads or the rounded head of the metal line ends.

I was thinking about buying a new cold start injector and trying to find a new line as well, $$$....

Ideas? Tips?
