Why leave a diesel running while filling it up?

    Haven't heard anything about the diesels, but at a couple of tech classes I've attended there have been check engine lights come on from filling up with the vehicle running or key being on with gas motors. It results from evap system codes being set. Also the fuel gauge will be delayed on getting to full from the anti slosh module

    Job 1 Build dates 01-07 thru 06-07 First builds of the 08's. Lower valence in front on front bumper much shorter than later job builds. Radiators would leak, most should be replaced under warranty by now. Also there was a recal for a venturi T to be added to keep the radiators from...


    I don't know if this has any good info between the jobs. But as far as the hard starting stuff goes. I read one not to long ago about this 2008 truck that had a hard time starting. I'll see if I can find the thread.

    I don't know about the common rail starting quickly. A lot of 08's I read on other forums this past winter had a lot of hard starting issues. But I think most of them were Job 1 trucks.

    I think that's why he didn't list the 6.4L. But yeah you're right, when we had the streak of all those cold days this past winter my truck started up just fine. A couple of times I waited till the light went off which took about 10 seconds. Then other mornings I just fired it right up. But then again my truck was fairly new then.

    If I was to buy a new truck it would be a glider, pick up a well put together pre egr and roll it. Some of the big company's are starting to go this route. New truck with zero extra crap on it. CA is only state that sounds like there going to have issues in future. Let the bottom feeders company's go in and out for penny's per mile.
    To bad you couldn't get pickups in a glider kit.

Luckily, I managed to switch to an 05 Volvo which doesnt have the DEF. So i can just fuel up, take a piss, and go instead of having to buy those damn blue boxes. and BTW, my truck idles nonstop (when i'm not driving) every day 5 days a week at least.
    in a passenger vehicle that's just daily driving, DEF usage is far less than a fully loaded commercial application.

    I modify all of my vehicles, so if I purchased a truck that used DEF, I would just delete all that shit anyhow

    5.9 cummins 12v's, 24v's and cr's fire up at any temp with zero issues.

    The three duramax powered trucks we have are a pain in the ass when temps drop around freezing.

You can optimize part of it with piston and injector design and injection events and take care of the rest later with catalysts.
    YUP YUP!

    This is why Ford and GM are schooling Dodge in the power and fuel mileage department with their latest offerings.

    Cummins is going to have DEF in 2012. Hopefully we'll see the power and mileage increases too

    Ford owns Cummins. Duh.

    Our "emissions solutions" group in Indiana handled the DPF and SCR component development, EPA cert, etc. It was my job to make it all work, fit, stay legal within the bounds of the EPA certs and be as user friendly as possible in this application. Starting with nothing but engine models and datasheets me and my design engineer (ProE expert) had that complete unit designed, built, dyno tested and in a rig in 12 weeks with a full wiring harness and control system.

    And it beat the shit out of me mentally.

    I foresee a jump in used heavy equipment prices in the near future, semi's, off road equipment, everything that has a diesel engine. Are you seeing a loss of fuel efficiency any? I think if they did lose fuel efficiency that may be a bigger turnoff than the increased price that's sure to accompany all the new emissions regs.
