Petrol pressure regulator, directly insertable to be installed in the fuel basket of the tank of models such as the Fiat Panda 169, Fiat Panda 100hp (always check the presence of the original model in the tank) without any modification which allows you to adjust the petrol pressure from fine to 5.9 bar instead of calibrated at 3.0 - 3.5 bar like the original. This regulator allows you to carry out the turbo transformation while maintaining the original injectors, without necessarily having to create a second line for the fuel return. Once the original fuel pump basket has been dismantled, the original regulator is removed and ours is installed in less than 5 minutes.
