The FP-321 Series Version 2.1 makes priming the fuel system of a diesel engine easier, faster, and safer than manually priming during routine filter changes. It pumps fuel into the lines to purge trapped air in the main feed line, primary filters, secondary filters, and engine. The bypass protects the system from pressurizing beyond the preset.
