Update:Still having issue with filling car, went back and looked at reply's and saw that there maybe a difference if the car was running while filling. I took the car to the same station and pump I have been using and left the car running and it never shut off. went back to the same place shut the car off took about 20mins. to put in about 4gals. Went back a few days later and left car running filled and the pump never shut off.Thanks for any feed back
