In addition, the likelihood increases that the gasoline pump is broken. The mechanical can fail, since you will have to install the fuel supply valve either before the pump itself, or after it. In the first version, the fuel pump will have to work “for dry” and therefore the valve is quickly erased and the energy efficiency of pumping equipment is reduced, in the second case the pump will constantly be forced to put pressure on the closed valve, which will lead to a breakdown of its seals and membranes. It should be noted that the electric gas pump will not be disconnected when the car will go by gas. As a result, the installers often turn off the nozzles. This is dictated by the fact that, in order to turn off the electric pump, you need a computer’s computer, and this is not quite simple and often far from everyone’s involvement. In addition, if in the machines of European models, this is possible theoretically, then in Japanese cars in no way.
