1987 Mercruiser 4.3/175. Found this hose that came loose from the carb. Common sense says it goes to the elbow, but it is way too short. Can I splice in a small piece of hose? Happen to know what size that is?
You will likely find that the other end of that hose goes to the Fuel Pump, and is there to prevent any Fuel from a leaking Pump Diaphragm, spilling into the Bilge, by diverting it to the Carb.
By now the Hose is likely stiff and inflexible, and should be replaced. Again, getting the Hose from a Marine Dealer, should insure getting one that is USCG Compliant, not oversize Windshield Washer Hose
Yup, clear so you can see if there is fuel in it, but don't use the clear hose you find at the hardware store on the reels. That hose is yellow so the know it's approved hose by a quick glance.

Safety inspections will specifically look for the yellow tinted hose to ensure it's fuel proof.
Clear Tygon will stand up to the fuels, but the cheapo PVC clear tubing (same stuff they sell for fish tanks) also available in the HW stores wont do well with the chemicals. Problem is, it's hard to distinguish the PVC from the Tygon, just looking at them.
