Gas pumps shut off prematurely

1651 Views 22 Replies 12 Participants Last post by  FJ-6MT
At almost any gas station I use, the pump shuts off when the tank is about 3/4 full. Restarting the pump gets another gallon or two. A couple of cycles and the tank is actually full. Obviously not a showstopper, but pretty annoying. This is a fairly recent development, but not tied to any work on the vehicle. Any ideas about what's going on and how to fix this?

The auto shut off is to stop you from ruining your charcoal evap canister by over filling and flooding it with gas.
That’s my guess… only because you said 3/4 full + 1-2 gal = full. It’s a 19 gallon tank. Your really at 17-18 gallons when the pump shuts off.

Could be I oversimplified the issue? I had no idea so many had this complaint. :unsure:
