    Okay that’s good so this actually might be the problem I really hope so wallet is really hurting. They just called me back saying they replaced the part at this point just waiting till the morning to see if the truck will start.

    I dont see how something that is past the filter could cause it to drain overnight.

    I’m really thinking it’s my injectors. I believe it’s my injectors all along. They gave me a faulty injectors when they did my inframe or didn’t put them on correctly.

    If you have a leaking injector your oil level will rise and the oil will smell like diesel.
    Like someone else suggested replace the check valve or ask them to test it if they can.

    Okay I will. They called me today saying they bleed the fuel system and ran it hard, to try to get the air out they believe it was air. Becuase they changed the quantity check valve and air most of gotten in. So now waiting till the morning to see how the truck starts and acts.
