    Antifreeze in fuel.

    Thanks a lot gentlemen. I am fighting with the “stealership” right now. Their telling me it’s a bad water separator.

    Antifreeze in fuel.

    Just curious. How would the antifreeze feed back into the fuel from the cup? Wouldn’t the antifreeze mix with the oil too? I’ve seen cracked heads and I know what you mean about the consumption. But you get smoke out the exhaust and oil in the antifreeze. Sent from my iPhone using Tapatalk
  3. Hello gentlemen. I come to you with a dilemma that has stumped both us and the stealership. Our 2016 Mack granite mp7 engine, Allison trans, is getting antifreeze in the fuel tank. I know this because it’s coming out of the water/fuel seperator. My mechanic is telling me that it’s the injector cups leaking back into the fuel, but that’s impossible right?
