Why are semi fuel tank fillers not designed the same as automobiles?

    Semi fuel tanks just have a hole with a scree cap while automobiles have it to where you insert the nozzle which is held steady and stops when the tank is actually completely full. No worries about spillage or nozzle falling out. Why aren't truck fuel tanks designed the same way? Is it to save a few dollars or because truckers cried when they made it better and wanted the primitive design like the 80s style trucks they drive around in? I don't understand that fascination I wouldn't buy a 2019 car that looks like its 40 years old but that's another topic.

    No standards set for the nozzle sizes on pumps.

    Truck diesel pumps also pump a lot faster have to displace the air faster

    Well if you fuel at the pumps designed for trucks, the nozzle has a nice lip that catches on the tank and it doesn't fall out, they also pump about 3 times faster than the car pumps.

    The nozzle won't fall out if you use a tarp strap to hold it in.
    If the nozzle jumps out, that's your fault, not the truck manufacturer.

    Not all of them have a nice lip. I am just saying its easy to fill up a car you stick it in and pull it out when done like sex.

    I think they make medications for that now. At least that’s what I heard. I have no practical experience with it.

    Please don’t ask my wife.

    Hahahahaha

    Not that many years ago some cardlocks had a nozzle that was 1.5 wide or so .. also when draining a tank for repairs they often use a fair size hose to siphon our the fuel .. another possible reason is the current setup seals better in case of a rollover or accident than it would with a car style filler neck

    That’s exactly why. The filler necks cause fuel to backup and you get wet feet. My old ‘41 pickup can’t take fuel at full volume from pump. Got to dribble it in. Old pumps moved less volume
