    John, I know what I'm talking about. It's located on the outlet of the ecm cooling plate, but not all had them. I've installed many on N14's that didn't come with one.
     
    John E. Thanks this.

    In my 5 years of owning an n14, injectors have been the biggest problem. Always carry a pair with you

    Speaking of fuel lines. Keep a common copper compression fitting to repair any fuel line leaks from pump to head and back. Watch the areas where the fuel lines vibrate against what used to be insulated clamps to repair or replace before failing.

    I've replaced many N-14 injectors and sure can't say it was a 30 min job. Maybe in a shop, not in no parking lot.

    I always carried a spare injector, several 12 point sockets, 3/8", 7/16", 1/2", and 9/16" --- deep sockets with me. May have been all of 40 minutes changing them unless it was no. 6. It was tougher to get access to that one. Quick hands probably made the difference, easytopleez33. You know what I'm sayin.
