Reverso Marine Fuel Primer FP-321 – Left to Right- 22 psi – 12V

Reverso FP-321 12V Fuel Primer

Featuring a specialized Fuel-Prime architecture, the Reverso FP-321 is the definitive mechanical solution for diesel technicians requiring a high-pressure physical bridge to fuel safety. As a premier Reverso fuel primer, this unit utilizes a 12V gear pump to deliver superior hydrodynamic priming for large diesel engines and filtration systems. The hardware architecture focuses on technical flow, ensuring this Reverso power system provides a Left-to-Right fuel path to facilitate rapid air removal from the fuel lines.

Technology-driven mechanical performance provides total protection through a pre-set pressure relief valve that prevents system over-pressurization during the priming cycle. This Reverso marine primer features a compact design to mitigate space constraints in tight engine room configurations. Reliability is reinforced by the non-corrosive brass pump head and high-torque motor designed for heavy-duty fuel service. This unit is the premier choice for mariners prioritizing professional maritime power and rapid fuel system recovery.
