Quakertown (Hunterdon County NJ) Fire Company Antique Engine 91-61. Engine 91-61 is a 1969 Mack CF Pumper with a 1000 GPM pump and a 750 gallon water tank. The body was refurbished by Grumman in 1990. The Engine has seating for 4 with 5 pre-connects. Due to its age and lack of safety features, the Engine has been moved into third line engine status as it has served our service area and company well. It was the first-out engine for 27 years until it was replaced by the 1996 Mack Saulsbury Rescue Engine.
