Can't tell what's wrong from photos, but it's a simple system. Hose goes from washer fluid reservoir to a spot under hood where it's split into two hoses, and goes to two nozzles.
Follow the hoses, replace what's broken or cut, or just disconnected.
These hoses are inexpensive, don't buy a $5 fitting to patch a section, when you can replace it all for $6-$10 worth of new hose.
Anyone ever pull Romex wire in a house. One way is to attach new wire to old (tape, wire), and pull far end of old wire. Might work for this rubber hose too. Lubricate close passages with silicone spray.
May be worth a try, worse case, go back to removing bumper, liners, etc.
