Hi, my renaul 19 RT 1.7 F2N (French) on me. The empty pump was broken with the module siemes. Can I replace it with another? What do they suggest? The only home of spare parts that has it in resistance (Chaco) asked me for the original (Sosmes) $ 3000 (three thousand pesos). I almost died. Please, could you advise me any way out of this problem? Thanks.
