Vapour Recovery Nozzles (VRN) at the servo Thu Nov 29, 2012 10:53 pm

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...
