Fuel injection pressure regulator POLINI Yamaha T-MAX 500i 2.5–3.5 bar

Polini injection pressure regulator for the fuel system, suitable for the Yamaha T-Max 500 maxi scooter with gasoline fuel injection. This Polini fuel injection pressure controller raises the pressure in the injection system from the original 2.5 to 3.5 bar. When tuning measures have already been taken to increase intake flow (improved air filter, exhaust system, or injection module), installing this Polini fuel pressure regulator is strongly recommended. The performance increase is mainly noticeable at high speeds and full throttle.
