Are you sure that the fuel is good???
You didn't have a problem till after you put the new fuel in right?
A tanker can get a load of hot fuel or bad fuel and then drop it in the station tanks.
We had a loading terminal that opened a wrong valve one time and about 4 trucks
loaded fuel and were headed to stations around Florida. Should have seen the terminal scramble trying to get in touch with those truck drivers before they dropped thier loads of fuel in to the stations. Then all the fuel at the stations would have been contaminated too. I would be checking the fuel first, maybe in to gas cans and put new fuel in. If you find it is the fuel the station is lieable for your cost$$$$.
