I posted this earlier but I don't see it so here goes again. If you have an injector from a 7.3 with crossed threads the thread is metric #12 1.50 pitch. I used a snap on rethreading die,tap and thead file to fix it. Everyone should own one of these kits. I have used it a number of times of the past 25 year and never had it fail. I is not a regular tap and die. It just fixes damage threads. I first files it with the correct side of the file then used the die nut. Just for saftey i ran the tap in the nut on the line even thought it looked fine with a mirror.
