fresh water pump,macerator pump

[10meterman]

I'm needing to replace my freshwater pump and macerator pump, vacu flush head, current pumps number ,freshwater (Jabsco model 31755) macerator pump (Jabsco model 18590 ) are these original pumps, is there upgrades ,should I stay with something close to the original? seal kits ,bellows for the toilet itself ,should I replace all the waste water hose while I'm at it? My baby a 1990 ten meter international, I will never get rid of her ,,so I want to do what's best for her.

My toilets are different but I have two macerator pumps and have rebuilt both of them, parts are available. I re-plumbed both my heads using schedule 40 pvc which solves the odor permeability of flexible hose and rebuilt jabsco macerator pumps.

Note wore rubber gloves until old nasty hose removed as well as when working on macerator pumps.
