diesel fuel nozzle

I don't use them. I have to be sooo careful or I end up with a big mess. If you get diesel on your shoes, socks, pants, etc you will be smelling diesel for the entire trip. And if it then transfers to the floor mats . . . . .

Funny thing, my '96 F250 has tanks that fit the large diesel nozzles. Never had a problem at truck stops.

My 2000 F250 would not take the larger nozzles, not sure when Ford changed. I used a tail pipe expander to make the hole bigger so larger nozzle would fit. Now I'm run into the ones with the ring around the end and I have to hold it in place. May have to see if I can expand it a bit more.

I pulled into a truck stop on Interstate 5 south of Sacramento as they advertised a fair price for diesel. The nozzle wouldn't fit my diesel SUV so I headed to the car pumps. Over a dollar more per gallon! I headed further south and hit a Loves truck stop and their regular pump prices were closely aligned to the truck pumps. They have earned future business from me.

Truck stop diesel pumps are made to fill very large tanks (18 wheeler trucks) and the pump nozzle is larger than the normal regular vehicle fuel pumps. The reason it is larger than normal is to be able to fill those large 18 wheel tanks much quicker.
I believe Dodge Ram trucks were the first to adapt the smaller trucks fuel tank fill opening to be able to use the truck stop pump nozzle. Don't know if ford or chevy have adapted over the years.

My 04 F250 will accept the larger nozzle. I don't use it much because of the higher amount of foam it creates.

Just beware. The tank will fill up rather quickly.

I have an auxiliary tank and it is wonderful to have those high volume nozzles.

Yep it sure is.

Ummh...I stopped at a truck stop to fill up my Ram CTD years ago and got the nozzle stuck in mine. The nozzle was bigger than the nozzle at a normal diesel pump. It took a few minutes to finally work it loose. Things may have changed since then???

I use the big-boy pumps all the time, the bigger girth nozzles fit with no issues on my 2015 RAM 3500.

I have a '02 Ford 250 Superduty and my fuel opening handles the large nozzles. Why mine does and other Ford's don't I can't figure out.

I use both type of nozzles when filling the motor home. I have seen some truck island pumps labeled with a warning sign that says flow can be up to 60 gals per minute. If you have a 30 gal or less tank, that means you could fill your tank in 30 seconds or less. This is the reason many truck fueling stations have a separate lane and pump for truck and RV'S. Your paying for the product but they have to clean up overfills. Even if I am pumping 70 plus gallons with a large nozzle I go slow because the foaming action filling at a fast rate will cause fuel to spray out as the pump shuts off. I like the smaller / slower fill rates better.

On older trucks like previous posters have said they tend to have smaller openings. My Ford's prior to 2007 would not accept the larger nozzle.
