truck stop diesel spout size

Just wondering...this came up in another post on fivers.

At truck stops, the diesel spout is typically much larger OD than the automotive spout.

Do the larger spouts fit in most new diesel trucks? In addition, some posters have said they fill too fast and usually burp out a lot diesel when done filling.

I have a stock 2011 chevy diesel. Wondering what the experiences have been at the truck stops and whether the larger spouts are an issue.

thx
  • My Dodge will take fuel from the big nozzle at full speed - I can hear the vent hissing! It's great to fill a tank in less than a minute.
  • One of the things that never caused me any problem with my 04 power stroke. It would tags fuel as fast as I wanted to pout it in.
  • Very simple with most vehicles. The metal neck the the cap fits is only about 6" long then connects to the hose. Remove the screws holding it to the vehicle, then remove the hose clamp. After removing pound out the neck baffle. About a 20 min job. once the baffle is removed you can fuel with the big boys. Just be careful how fast you run the pump.

    True - I believe that RV owners buy a small percentage of diesel at truck stops compared to their primary customers, that being the big rig drivers.

    If that is true, that's why their diesel pumps at a much faster rate than gasoline pumps - remember the big rig guys purchase many more gallons of diesel at each stop than we do and time is money to them so the faster they get their fuel and other things taken care of at each fuel stop,the faster they can get back on the road.

    Even with my 34 gallon tank in my Ram, it doesn't take long to fill it. I learned that the first time I filled it.
  • I have a 2005 F250, 6.0 and have no problem using the larger (truck style) spouts. As far as your tank accepting the larger nozzle… just give it a try. I suspect that all of the newer diesel trucks have the larger fill type.

    True, fill rate is much faster, however I have never had a problem with "splash."

    One thing you can do is just run the flow at a lower rate or when you feel your tank is nearing the full mark release the catch and manually control the nozzle. This is not that much of an issue as the tank will fill so quickly that the small amount of time in manual mode is next to nil.
