This tool is designed to hold the spring loaded boot back for you while you're filling your tank and or gas can.
The tool is the same size as your drivers license/gas card and being only 1/8" thick will fit in your wallet or a jacket pocket.
It is made of ABS plastic to prevent damage to the paint finish on your fuel tank
It's easy to use and makes filling up a cinch.
Slide the tool over the nozzle, depress the boot past the ring that holds the nozzle in place on a car fuel filler, and slide it over to lock the boot in place.
Yes I know that they are already out there, but I'd like to think that mine is better than the others and cheaper to boot, i.e. $5.00 shipped.
That price is for the lower 48 since I'm simply slipping the tool into an envelope and slapping a stamp on it. Anyplace else will be $5.00 plus shipping, i.e. whatever it actually costs me to do the same thing to places outside the lower 48.
Here is a video clip showing how easy it is to use the tool.
The first couple of seconds show how how you have to hold the boot back to activate fuel flow, followed by the EFN Tool in use.
