As a general rule, the 332 is fitted with fuel dump, the 333 is not.
That said, I agree with paull's and machinbird's comments.
Further, the jettison rate is approximately 1180kg/min. There was approximately 42.6k kg of fuel on board, - (BEA 1rst Interim Report, P.20) at LKP.
Even given a decision to dump fuel (which would have been both impractical (due time) and ineffective (there is no emergency in the QRH, and none I can think of that would require such action as an immediate need)), it is easy to calculate that there would have been a substantial amount of fuel on board at impact.
