    Greetings

    Sitting on the tarmac in Milwaukee a jet fuel truck pulls up to top us off. First the driver applies what appears to be a grounding wire. Next the big black hose comes out which must be the fuel.

    But then the driver d,rags out two very thin hoses that are attached to each other. One is red and the other is green.

    What are they using those hoses for?

    Thanks

    Sure they weren't heavy electrical cords? Sounds like the overfill and grounding connections, I forget the name of the system.

    Back in the early 80's I drove a tarmac fuel tanker, things are probably different now. We always had dead man rope to pull or the truck would not continue pumping.

    I remember the rope, too.

    Maybe now it's an air-powered deadman.

    Seems unlikely though. The rope was simple, and easy to fix.....;)

    I assume one would be for vapor recovery.

    Skully system, check spelling....

    I do not believe that is what the op is referring to. Possible, but without seeing the connection... idk.

    On the military refuelers ive used, they were air powered deadman switches.

    This image jogged my memory. Our air powered dead mans did have two hoses.

    So it was probably the deadman.

    Thanks, that’s exactly what it looked like.

    A funny (or not so funny) aspect of what I saw was that the driver hooked up the ground wire, then hooked up the fueling hose and started fueling. It wasn’t until another fellow walked up and spoke with the driver for a couple of minutes that they both pulled these “dead man” hoses out and attached them to the plane. I am guessing those are supposed to be connected first?

    Well, I'll be dogged. They really DO make an air-powered deadman for refuelers. Thanks, blackshack!
