It is not a huge leap to think that strong vocal support might also entail material support - from Wikipedia:
American talk radio host Michael Savage became the first popular media figure to publicly announce support for the EDL, stating, "How does England take the Islamofascists spitting on their war dead, without letting the English Defence League wade into them with pipes and beer bottles, I'll never understand".
In October 2010, American Tea Party activist Rabbi Nachum Shifren, travelled to England to speak at a rally. In his speech, he called Muslims "dogs" and told the EDL that "history will be recorded that on this day, read by our children for eternity, one group lit the spark to liberate us from the oppressors of our two governments and the leftist, fifth column, quisling press, and that it was the EDL which started the liberation of England from evil."
The Canadian Jewish Defense League has held a demonstration in support of the EDL, saying that the two groups will "take a stand against the forces of political Islam". The Canadian Jewish Congress has opposed the alliance.
Hard to prove there's financial support, but not unimaginable. Certainly not to the extent that the mere suggestion warrants cries of antisemitism.
