How to fill up without getting it on the damn car?

I have to pull the "foreskin" back and invert the nozzle upside down to fill my '65. Slow fill didnt trigger the vapor recovery cutoff, but I had to keep an eye on the quantity so I wouldnt overfill. I bought it with a peeled paint trail down the side of the car from the cap so its been an issue for a long time.
