As long as they’re kept reasonably far away (I imagine a few meters would be enough), it should be fine. The internal combustion engines driving on all sides of the pumps don’t usually ignite it, neither do trolley bus wires (which occasionally let out fairly sizeable sparks) or just general overhead power lines. There’s also no oxygen in the storage tank or feed lines, so even if the vapours catch on fire, it really shouldn’t explode like in the movies.

There is high voltage electricity coursing through gas stations at any given time. There is not real concern here.
