Post subject:  The skinny ones sure do like to belch...
Hi folks,

On our 1500 mile trip in the last two days, I managed to belch fuel all over the ground twice when refuelling with the skinny "auto diesel" nozzles. The skinny nozzles leave a good amount of space around the larger flapper valve, and it seems that there is not enough pressure buildup at the nozzle outlet to trigger the shutoff. Some pumps seem worse than others.

Is there a trick to refuelling cleanly with the skinny nozzles without leaving a nice coating of #2 down the side of my CRD and all over the ground? The only solution I've found is to slow down as I know I'm getting close, and look/listen to determine when the fuel level is crawling up the filler tube. If there's a better trick to this, I'm all ears!

First I've heard of this happening. Never had a problem myself in about a hundred fills or so. Is it possible your vent is pinched, clogged, etc.

I've had it happen twice now so I watch the amount I'm putting in a start listening when I think it's close. I've also come across two stations that had notes on their diesel pumps stating the nozzle may not shut off.

I've run into wide nozzles that are bent a beat up at truck stops that WON'T fit into the CRD.

Back spray seems to happen pretty regularly to our CRD, it really depends on the nozzle. I always get some paper towels before filling up because I've come to expect a mess.

Of course, with 100% Biodiesel, the mess smells nicer! But I splash-mix (!) diesel in this time of years....so more stink.

I have had it happen at one station in particular...now I just set it on the slow notch.

I normally do the slow notch all the time to minimize foam

sad to say the only station I am aware of around here that sold bio ( was only 5%) is now just reg dino ... they taped over the bio part of the biodiesel sticket with tape ...

One time in in 55k miles, I suspect the pump flow rate was set too high.

I've had this happen several times. It seems to happen to me when the fuel foams very little :D That's normally a indication of a quality fuel. It's one of the things that is measured in European fuel standards. I've been buying most of my fuel from Meijer and it's labled "permium diesel". I've used it in my diesels for over 15 years or whenever they came to Columbus with good results. Also their stores are located in competive areas and usally it's about the lowest priced around :lol: But that's a realative term :?

On these overflowed tanks as I read your notes is when you got your best mileage. Part of your increase could be the fuel. On my last jetta tdi (99.5 A4 platform) I actually got two tanks in the low 70's :shock: I attribute most of it to fuel from Florida and Georgia. My experience is the further south you go the better the fuel at least on the eastern part of the country. The fuel we get in Centeral Ohio seems to be the worst quality on the plannet :lol: Meijer fuel is supposably trucked in from Kentucky :P

Interesting! I never thought to associate the fuel quality, lack of foaminess, and less reliable shutoff problems all together! Quite interesting... The consensus seems to be that this can indeed happen when the conditions conspire together - certain fuel characteristics, pump flow rates, and shutoff pressure setting. There's one pump by our house with a skinny nozzle that always overflows when left to its own devices, and another one which works fine.

When on the road at an unknown station, I'll just be sure to manually fill for those last few gallons for the skinny nozzles. Thanks for all of your responses,

I was pretty suprised to see a full spray of diesel shooting toward the pump when filling up at a station in Madison. I thought it was a faulty sensor. Good thing they had a car wash. Thought I'd get some grief for soaking thier station but no one seemed to notice- hehehe. I don't go to that station anymore. Good thing Diesel is not a fire hazard and it takes 1700 degrees to ignite it :?
