Your fuel line fitting has cracked or perished and you're stuck at the marina with a weeping connection. This is the 10mm (3/8") plastic hose barb that slots onto the MGC340 tank fitting. Made for Mercury and Mariner outboard fuel tanks manufactured from 1999 onwards. Push it on, clamp the line, and the leak is done. No guessing, no cross-threading, no waiting on a national chain's six-day shipping
