What to do if my Reverso FPS-80 Control Unit has low or no flow?
- DDr. Kaitlin ClayAug 4, 2025
If your Reverso Control Unit experiences low or no flow, consider the following potential solutions: * Check if the pump is worn or not running. * Ensure the pump and filter are primed. * Verify the fuel supply or discharge line isn't blocked; check the alarm. * Confirm the lift isn't too high. * Inspect for air leaks in the fuel supply to the pump. * Ensure the inlet or outlet valve is open; check the solenoid valve. * Verify the foot (check) valve isn't installed backward. * Look for air leaks at the inlet. * Check for improperly installed or dimensioned piping. * Service the fuel water separator to see if it's clogged.
