What's on Your Engine #24? - Pony Suction Fittings
By President Mark Davis

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.
A 2-1/2" x 3" double-male is needed to make this 3-inch suction hose connect to the pumper's auxiliary intake.
If you carry "pony" suctions make sure that you know the coupling size ahead of time so that you have the correct adaptor if needed.
