    I have a 2015 freightliner cascadia with 150 gal on left side and 120 on right. Here recently the tanks have not been equalizing. The right side is about half to 3/4 full when the left is reading empty. Any help on where to start trouble shooting would greatly be appreciated. Thank you

    Had the same problem. It was the tank vent. You need to replace the vent on the tank that has the 1/2 to 3/4. Its located on top of the tank. May or may not have a short hose that runs down the back of the tank

    Definitely sounds like a tank breather issue

    Check and make sure the Equiflow system hasn't been removed from either tank. I drove one like that where it was removed and replaced with a street el, and that one did the same thing. The tank with the gauge had a much lower level than the other one. I only ran it a bit over a month, and was always worried it would run out on me. It never did, though.

    Alright guys I took off the valves and checked them and they were both plugged up. I put two new ones on with new hoses so hopefully that will fix the problem.. Thanks everyone
