FERRARI PUROSANGUE F175 Fuel Tank

the fuel tank for the Ferrari Purosangue (Project F175) is a highly specialized component designed to fit within the vehicle’s complex transaxle architecture while maintaining a low center of gravity.

1. Technical Identification & Specs

• Fuel Capacity: 100 Liters (approx. 26.4 US Gallons). This is a generous capacity for a Ferrari, designed to give the V12 Purosangue a respectable touring range despite its high consumption.

• Design Type: Saddle Tank. To clear the central torque tube and the rear-mounted transaxle, the tank is split into two main lobes connected by a crossover pipe.

• Material: Multi-layer high-density polyethylene (HDPE) with integrated EVAP (Evaporative Emission Control) shielding to meet 2026 global emission standards.

• Part Number Series: Components for the fuel system typically fall under the 917xxx or 928xxx sequences in the Purosangue catalog.

Because the fuel tank is a safety-critical, non-serviceable sealed unit, replacement is costly.

3. Key Installation Notes

• Chassis Disassembly: Replacing the fuel tank on a Purosangue is a “major” service event. Because it is nestled between the passenger cell and the rear transaxle, the rear subframe or the torque tube often needs to be partially lowered or removed to gain access.

• High-Pressure Fuel System: The V12 engine uses GDI (Gasoline Direct Injection) with pressures up to 350 bar. Any work on the tank or the low-pressure lift pumps must be followed by a system bleed and pressure test using the Ferrari DEIS diagnostic tool to ensure no leaks occur near the high-temp exhaust components.

• Fuel Flap Mechanism: The Purosangue uses an electronic push-to-release fuel door. In 2026, some owners have reported the actuator failing; this is a separate part from the tank itself but is often diagnosed at the same time.

4. 2026 Maintenance: Fuel Quality

With the F140IA V12 engine, Ferrari mandates the use of 98 RON (Premium Unleaded 93/94 Octane in the US).

• Ethanol Warning: While the tank is designed to handle E10/E15 blends, if the car is stored for long periods (common with Ferraris), the fuel can phase-separate and damage the internal lift pumps.

• Tip: If the car is being stored for more than 30 days, using a Ferrari-approved fuel stabilizer is essential to protect the internal seals of the 100L tank.
