In many of the US States, and perhaps in other countries as well, they've been using petrol vapour recovery nozzles (VRN) at the servos (gas stations) for ages now which are designed to reduce the escaping fuel vapours around the filler neck of most automobiles. Of course, not much thought was given to their ease of use in motorbike tanks. At the nozzle end there's an accordian rubber boot which when retracted is designed to allow fuel to flow but to not allow as much nasty fuel vapours to escape into the atmosphere as the nozzle is pressed hard and deep into the receptacle of the vehicle as the trigger is pulled.

Of course when using these buggers in a motorbike one has to use two hands; one to steady the nozzle, aim and pull the (often hair pin) trigger, and one to pull back on the accordian rubber foreskin. It's a pain. So I have this cleverly designed little plastic device about 3mm thick. It measures 70mm x 89mm (2-3/4" x 3-1/2"). The pear-shaped cut-out in the middle of the flat, plastic rectangle slips over the nozzle and as you slip the card up or down against the nozzle it locks into the appropriate slot on the card, holding the boot back - voila! A one-handed operation. This reduces time, allows you to fill the tank to the brim, and eliminates spillage and waste of a precious and expensive resource, not to mention keeping your Duco in top nick.

Does one lose karma because he or she has just allowed noxious, gaseous fuel vapours to pollute the pristine air round America's big cities? Not a chance. In California, Massachusetts and many other "forward thinking" states, the VRN are required, but in some cities within the same state, or just up the road in Oregon (or down the road in New Mexico, Mississippi or Louisiana) they don't know what the flip you're talking about.

The card's dimensions are 70mm x 89mm x 3mm (2-3/4" x 3-1/2"). The larger hole is 32mm (1-1/4"), the middle hole 25mm (about an inch) and the smallest, which is usually not needed on most pump nozzles, measures just 19mm (3/4").

If I use it I can gurgle all 6.6 US gallons into the tank. If I don't I barely get 5-3/4 into the bloody tank. Here's a piccy with my keys next to it for size reference. I hear tell a large, hardware store-procured clevis pin works a charm too. Some bloke in Portland, Oregon sold me this for like three dollars about ten years ago. I took it home to OZ in '06 but realised we're still in the stone age Down Under as far as vaporous governmental "forward thinking" goes. Besides, the Kiwis over on the other side of the ditch wouldn't notice a bit of our gaseuos OZ fuel vapours drifting and settling upon their fine islands.

Hey, I've an idea, what say we start calling them Hobbits instead of Kiwis for a change? What with the new-found hype and interest in Hobbits and Middle earth and all...

Cheekily yours,
TWB

nice one dazza ...a good find

i seem to recall back in the late 70s and or early 80s that amoco had a final filter fitted to their equipment and some others suppliers had some sort of gaiter round the nozzle ..a bit like you describe near the handle end or was that shell ? i recall it being red or yellow ?

i dont think it was for vapour recovery though ..although it would have limited the vapour dump to the atmosphere .

would be marvelous over here in nzed to be able to realy fill up properly

just filled up today ....40 liters at $2.15 / litre ( for the not so good, low grade stuff ) ...havent found the 98 ron good stuff round here yet ...but shudder to think what its worth .

Across this country petrol prices varied widely. I tried always to use premium/supreme and paid anywhere from $3.49 a gallon in the Deep South to $4.09/$4.29 in the Midwest and the New England states, up to $4.79 during Hurricane Sandy's aftermath in New York state. It's currently $3.59 at the local servo down the street for premium Shell here in the Pacific North Wet.

That's anywhere from $.92 to $1.25 a litre straight across from the US dollar to the OZ dollar...When I left OZ in June it was about $1.65 per litre or $6.25 per US gallon equivalent.

This simple little tool helps me get more of the go-juice into my tank.

TWB, did I miss something? You referenced the PNW - are you back in town?

Yes, Clubbie, got back already. Am going back to work (and toil) on Tuesday the 8th in Seattle. All up it was over 17,700 kilometres and 54 days on the road. All of it fun and all of it memorable. The RT was typical BMW, in my long-time experience with them; flawless. An update will follow on my ongoing "Ride So Far" post. Just trying to unpack and sort at the mo'...
Cheers.

This tool you describe sounds strangely familiar.
Wouldn't be white in color, would it ?

I've been selling it since 2010 on ADV rider in the vendor thread.
Might you be one of my customers ?

Paint them different colours (colors).

Stencil the BMW logo (or other maker's logo).

Make them out of aluminium (aluminum) so you can add a bottle opener.

Make the corners into blade and phillips head screw drivers.

Stencil inch and millimeter markings on the edges to make a small ruler.

Stencil inch and millimeter markings on the edges to make a small ruler. Best idea of the bunch.

I have been selling these for $5 each since 2010, when they used to be black. People complained that because the black disappeared visually against the black of the boot they forgot them on the pump.
My local supplier stocks ABS plastic in black and white, so white it is.
