Check the pump before pumping. Several have the security tape cut or peeled off. Not sure if the pump has been tampered with, but the one I used seamed to be accurate. Also, without the security tape you can not be sure someone has not installed a credit card skimmer inside, so check your credit card often to make sure you are not getting bogus charges.
pump had trouble with credit and then other did not print receipt
No longer in service due to fire.
Great
