In Jersey, it's illegal to fill your own tank. You HAVE to have an attendant do it.
Ah that sucks. Diesel here doesn't meet the same classification and gasoline and propane so we can pump out own diesel but not gasoline...
Have a little more time to clarify, here in Oregon class 1 combustibles have to be dispensed by a attendant, diesel not being a class 1 combustible we can pump our own. I don't think a lot of people here know that and the ones that do either don't mind waiting on a attendant or are too lazy to do it them selves.
The disclaimer sign I mentioned earlier does not specify people who pump their own fuel or if a attendant does it, it just says the station is not responsible for a 'misfuel' and it's signed 'management' not shell corp and is taped to the multifuel pump.
To the OP, hope things turn out alright for you, regardless of wether or not you need new parts or if they have a sign similar to what they have up where I fuel I'd go in and try to get the owner involved to try to make sure it doesn't happen again. And if you do need new parts its probably pretty obvious your going in.....
