Report "I have a 3406 E model . I recently changed the injector cups and seals and one injector, because it was getting fuel in the radiator. One month later it started doing it again. So we found a couple of bad seals **** up from when we installed them.. Now we are getting water in the fuel tanks. I thought it was from a station...Because it wasn't showing hot.. Now I have noticed the radiator is about 3 gallons low. Can you tell me what the problem could be????"
