My 2001 Chevy Prizm recently has this problem: when filling the tank (with #87
gas), the gas pump nozzle will automatically jump (shut off) about every 0.4 gallon or so, before the tank is filled. This keeps happening until the tank is actually full. I tried many different gas stations, I tried turning the nozzle upside down or any other angle, not helping. I noticed that foam comes up as gas goes into tank and that may trigger the nozzle's auto shut off mechanism... Anyone has similar issue before? Any idea why this is happening (never have any problem for ~5 years of having this car) and how to fix it? Thank you very much!
