According to one of my source at the office of Prime Minister Benjamin Netanyahu, between 72% and 80% of French-Israeli have voted for Likud in the general elections of 17 March 2015.
These figures are based on a private study that the margin of error is 2.5%; which means that in the worst case, the Franco-Israeli were 69.5% choose the Likud and in the best case 82.5%.
The study was conducted on a representative sample of just under 1,000 people.
The study, however, did not say how it is divided the remaining votes.
Franco-Israeli community registered in the consulates is estimated at 150,000 people (half of whom are of voting age). It is also estimated to be added between 75,000 and 100,000 people more that are not on the consulate lists (people whom never recorded at the consulates, those present in Israel for a long time and have not been linked with the consulate since 10 years or more, etc…).
To recall and no direct link, note that during the French presidential elections in 2007, Nicolas Sarkozy had obtained 91% of votes from French-Israeli voters.
