From six-inch down to 2½-inch intakes and six-inch to 1½-inch discharges, today’s fire apparatus carry an assortment of inlets and outlets—in many different locations—according to the tactical needs of the fire department. Apparatus manufacturers typically talk with departments about the standard inlets and discharges needed for a specific pump size and then add any intake and discharge configuration needed for the department’s specific situation.
Front Bumper Location
Grady North, E-ONE product manager, says, “For E-ONE, there’s hardly a standard inlet and discharge layout anymore because we design the pump modules for every truck we build.” However, North says the biggest trend in pumper discharges is full-width front bumper crosslays. “A few years ago, it was common to see a single 1½-inch preconnect in a front bumper hose well, but now a lot of departments are doing two full crosslays, which gets the hose down low and easy to access for the firefighter.”

North cites a pumper that E-ONE recently built for the Bloomington (IL) Fire Department that has two 1¾-inch crosslays in the front bumper, two 2½-inch rear preconnects on the left and right ends, one right rear 2½-inch discharge, two 2½-inch left side panel discharges, a four-inch right side discharge, a three-inch deck gun discharge, two six-inch intakes, and two gated 2½-inch intakes.
Mark Kopunek, product manager, KME, says the manufacturer has built a number of pumpers for customers wanting double preconnect trays in the front bumper. “We’ve done full crosslays for 1¾-inch hoselines,” he says, “which give better accessibility at ground level. We’ve also built multiple storage wells with multiple discharges and also a single discharge and a six-inch intake with five-inch plumbing back to the pump.”
Larry Segreto, vice president of Boise Mobile Equipment (BME), says his company builds a lot of wildland pumpers. “For our pumpers, gate control always is located at the outlet,” Segreto points out. “And, we don’t put intakes on front bumpers but rather 1½-inch outlets with local control, usually one left and one right.” BME typically will install two rear discharges on its wildland ri
