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

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

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?
