The sump in my bilge is very narrow too, and the best I have found is what the boat came with: one of these

but although it might just be narrow enough for you, at 56mm, it's 102mm long. Is there any scope for making a square-ish strainer that would fit across the whole sump, with a big hole in the middle for a hose, or even a through spigot? In other words, use the bilge itself as the strum box.
I think the one I have might be a cutdown version of this!
