Fitment and Maintenance Use

The Reverso FP-321-12-LR is specified for diesel engine filter priming, air bleeding, and routine marine fuel-system servicing. It is a 12V DC pump with fixed left-to-right flow, so its electrical supply, fuel-line routing, and 1/4-inch NPT female port requirements must match the installation. Confirm fitment using the engine model, serial number, and manufacturer service documentation before ordering.

Installation and Service Considerations

Install this pump only where 12V DC power, 1/4-inch NPT female port connections, and a left-to-right flow layout match the system design. The pump is specified with an intermittent-duty marine electric motor; follow the engine manufacturer’s service manual and the product instructions for installation and service procedures. Verify the engine model and serial number before service.

Before Ordering the Reverso FP-321

Confirm that Reverso Pumps part number FP-321-12-LR matches your marine diesel priming or air-bleeding application. Verify the 12V DC operating voltage, 30 GPH (114 LPH/0.5 GPM) nominal flow rate, 22.0 PSI (1.5 bar) maximum discharge pressure, fixed left-to-right flow direction, 1/4-inch NPT female ports, cast brass housing, stainless steel internal components, intermittent-duty motor, and 5.0 lb (2.3 kg) dry weight. Confirm compatibility with your engine manufacturer’s documentation before purchase.
