What's on Your Engine #24? - Pony Suction Fittings

A simple issue than can arise when using "pony" suction hose is that many come with 3-inch couplings which do not fit most intakes on a traditional FD pumper. These pony sections often were acquired from a portable fire pump or some type of brush/grass rig where they worked just fine. But....trying to connect a 3-inch coupling to the pumper's 2-1/2" auxiliary intake can be tricky as you work to find a 2-1/2" x 3" adaptor. So....nothing wrong with 3-inch suction outfitted with 3-inch couplings...just plan ahead if you carry that stuff.
