The washer pump? Yes, several amps. More current than you'd realize,
they are terribly inefficient. And noisy.

There are several fuel pump designs that will work with water! (not
the rotary ones, but there are designs that use a plunger with a
solenoid driver). They may do a better job doing what you want. (Big
may, not sure if they'd last an incredibly long time).
