What he said!  Very common question that I get and this is the correct answer.  DO NOT try to directly match the load with the breaker (or fuse if you insist) rating.

I would be very inclined to use a dedicated breaker for each pump and
make them about double what the pump draw is.  You're not protecting the
pump IMO, but the wire leading to the pump (so a dead short doesn't set
fire to your airplane).  The LAST thing I'd want is a spurious / false
break (particularly if it shuts down ALL my pumps.
I'd go for 15A or so ... Jim S.
