    I need your help urgently

    I have installed recently an old fuel pump for my car I do not know its make but it has a a small board with "transistor I suppose number D73" beside 2 diodes and 3 resistors. The mechanic committed a fault and reversed power polarity resulted in blowing the D73 and the diodes, how can I go about fixing the problem , and I can not find a substitute for the D73

    If the mechanic ruined it, are they not liable for fixing it? Do they have no other fuel pump available to them?

    Without knowing what the bad component is, and having no schematic to work from, it will be prohibitively challenging to find a suitable replacement.
