12 Volt vacuum pump problem

The unit that was in my car was 10 amps. it is correct. its a small squirrel cage motor only driving a small compression motor creating 18-22in of vac. If you're blowing that fuse continually many things could factor. Bad motor, or excessive heat in the engine bay (as heat rises with electrical devices current draw increases, also the fuse element is more susceptible as well). Things I would check first.
