74 Duster gas overflow

New pumps push fuel faster than the old fillers were designed for, and the neck doesn’t hold the nozzle at the right angle either.

You’ll either need to always fill at about half speed, or figure out a different way to vent the filler so you don’t get an over pressure to puke the fuel out.

I have the same problem with mine, it works fine if you’re patient but if you get in a hurry and don’t back off on the volume when the tank gets close to full it pukes it out.
