Buyers Products 50 Gallon Side Mount Aluminum Reservoir with Rear Ports features dual rear 2 in. NPT female-threaded suction/return ports. It's internally baffled to suppress sloshing and lower operating temperatures. The reservoir's aluminum body is light weight and extremely resistant to corrosion. The included mounting brackets wrap under the tank for added stability and support. Rubber-insulated stainless steel straps are also included standard to keep it secure. Each unit includes a chrome-plated polymer filler-strainer breather cap and a level/temperature sight gauge that can be mounted on either end of the reservoir.
