My Walbro pumps were stamped to use a 20a fuse.

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.
