Mine (installed by PO) had a long intake run from the forward head
intake, through the forward cabin
into the sail locker. Over time (and a couple of blocked inlet events) the nearly right-angle bends in the hose began to flatten out. Moving it was impractical (I really tried) so I replaced the hose with a spiral reinforced type that won't (so far) crush. My aft washdown also has a long run, but it's T'd from the aft head
intake with only a foot of hose. In other words, blow, definitely blow.
Also consider how you will be getting power to the pump - sometimes more hose is easier than more wire.
