It's always easier for the parts guy to get you the correct part when he starts with the correct information. Of course, if he was a real parts guy, he would have already asked for the VIN and he wouldn't work at Autozone anyway.
P.S. If you go to Advance instead of AZ, you can save about $10 on the pump. And don't forget to replace the filter.
