Pump relay – Ferrari F1 (4-pin)
The electromagnetic relay is responsible to turn on / off the hydraulic pump of the Ferrari F1 system. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the gears or clutch.
Please mind, that there are two different versions for the Ferrari F1 relay (30A with 5 pins and 50A with 4 pins). Check the car reference and compare the part numbers.
