I have a 1974 Ford F250 and I have an extremely difficult time filling the tanks at gas stations with the newer rubber boots on the gas nozzles. The physical shape of the older pickup truck gas filler opening is just not designed to work well with the newer gas pump nozzles. I have to pull back the boot with my hand and hold the lever at about 30% of full-speed.
Are there any products that I can use to make filling up easier? The only idea I've got is to buy a large external gas tank and fill up from there.
Here is a photo of the truck in question.
